OUTLINE

The Basic Interpreter Mode can execute the printer’s program in BASIC format enabling
applications such as performing stand alone printing. Since the emulation content is different,
there is limitation in the application command which will be described in the manual.

BASIC INTERPRETER OVERVIEW

SPECIAL NOTES

• SEMBL-BASIC has changed the partial specification based on ZBI of the ZEBRA. Details
may be found in the Instruction Reference.

• Input is performed at the half-sized alphanumeric character ASCII Code in accordance with
ANSI.

• The valid code range is 20
CR(0D
and HT(09

16), LF(0A16, ETX(0316), and BS(0816). Other control codes will be ignored after receipt

16) will also be thrown out. There is not a code limitation in the string quote and

16, 7E16, and partial control code. The valid control code is only

CHR$().

• When 2 byte code and half-sized code (80

16 . FF16) at shiftout side is used for the LCD

display data string, it might not be generated correctly.

• Command input and parameters that accompany the command will not differentiate between
upper and lower case. When command and command parameter are entered in lower case,
or with the mixture of upper and lower, it will be interpreted similarly as if it is upper case.

• Numeric mark has the following limitation:

• Other than decimal numeral, numeral marks of hexdecimal, octal, and binary is
applicable.

NUMERAL DESCRIPTION METHOD EXAMPLE

Decimal

10

Hexidecimal

16

Octal

8

Binary

2

Data string that is composed by
using numeric of 0 thru 9.

Data string that is composed by
using both numeric &H. 0 thru
9 and alphabet A thru F.

Data string that is composed by
numeric of &O. 0 thru 7

Data string that is composed by
numeric of &B. 0 thru 1

1021, -5, 0

&H3FD, &H8005, -&H5, &H0
&H8005 and -&H5 shows the same value

&O1775, &O700005, -&O5, &O0
&O700005 and -&O5 shows the same
value

&B001111111101,
&B1000000000000101, &B101, &B0

• Only positive and negative integral numbers may be used. Fractions cannot be
assigned.

• As for hexadecimal, the lower case mark is allowed in A thru F.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 1

• Integral numbers will be single-precision real numbers. Double-precision and
exponent mark is not allowed.

• The valid range of numerical value is -2147483647 thru 2147483637 (with code 4 byte value:

-7FFFFFFF

16 thru -7FFFFFFF16). When the valid range is exceeded, a rounded interpretation

within the valid range will be provided, but perhaps without the expected result.

• The maximum quantity of the digits for character string is 256. An error will appear if
exceeding the valid range.

• The definable number of numeric variable is at maximum 256.

• The definable number of string variable is at maximum 256.

• Both numeric variables and string variables can define the one-dimensional and two
dimensional arrays in the variable. In either case, the definable array element number is
defined in the number.

• Variable name is valid to 8 digits. Length exceeding 8 digits is interpreted by rounding off to 8
digits beginning at variable definition.

• Variable identifier distenguishes the upper and lower cases. In other words, variable WORK
and work, Work is all treated as other variable.

• Please assign the priority order by putting parenthesis at logical operation above 3 items:
e.g..IF (A = B) OR (A = C). 1 thru 32767.

• The line number is valid to 5 digits, and can be assigned with a range of 1 . 32767.

• The maximum times a line number can be programmed is 1000.

• The file number limit is that which can be stored in the extended memory cartridge. A memory
full error will appear if 512 KB is reached. About 32 byte will be consumed with each file.

• The following is the output format of BASIC syntax error during direct input (not RUN):

• 801 Syntax Error: invalid command (error detail explanation).

• Following is the output format of BASIC syntax error when running a program (RUN):

• 818 (110) Syntax Error: file not found.

ON ERROR

Function

Format ON ERROR GOTO <line number> ON ERROR GOSUB <line number>

Example

Usage of GOTO or GOSUB to indicate if the ON ERROR will be as same as the usual GOTO and
GOSUB. The original return point of ON ERROR GOSUB is the next line of the error detect line.

To return to the operation program after an error is processed using ON ERROR GOTO, indicate the
GOTO at the end of error process.

When running the SEMBL program and a printer error is detected once, jump to the branch instruction
ON ERROR. The involved setting of ON ERROR will be cleared.

To operate the error detection continuously, set ON ERROR again. The ON ERROR assignment is not
inherited from another SEMBL program. The ON ERROR and ISERROR types are similar.

Detect printer error when executing SEMBL program, jump to the assigned branch
instruction.

10 ON ERROR GOTO 200
20 operation program
100 END
200 PRINT “PRINTER ERROR”
210 BREAK
>RUN (when printer error occur)
result: PRINTER ERROR. break

DEBUG

Function Set/cancel the debug mode.

Format DEBUG <ON/OFF>

Example DEBUG ON

Set the debug mode by assigning ON. During the debug mode setting, TRACE and BREAK is valid for
standard operation. By assigning OFF, the debug mode will be cancelled and TRACE and BREAK will
not be processed. The default for non-assignment is off.

This command can be appied by executing direct input and providing line number.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 20

TRACE

Function Display the trace information.

Format TRACE <ON/OFF>

10 LET A=5
20 GOTO 40
30 PRINT “Error”

Example

40 PRINT A
>DEBUG ON
>TRACE ON
>RUN
result: <TRACE>00010, <TRACE> A=5, <TRACE>00020, <TRACE>00040, 5

By assigning ON, trace information will be displayed with the standard output by the following format
(<TRACE>trace information). The generated trace information will be entering the variable and the line
number. When the content of the defined variable changes, it will display as: <TRACE>variable$=new
substitution value. The line number will be displayed thusly: <TRACE>Line No.

By assigning OFF, output of trace information is completed. Default for non-assignment is Off. This
command can be appied by executing direct input and providing line number.

NOTE: Trace output from this command operates effectively only with DEBUG ON. No requirements are
needed for the order of assignments of DEBUG ON and TRACE ON.

‘ (APOSTROPHE)

Function Start the comment.

Format [form] ‘ [comment]

10 LET W=10 ‘Initialize

Example

20 PRINT w’;W+1
>RUN
result: 10

This command can be described in the optional location hereafter the line number. From this command
to the end of the line will be treated as comment, and will be ignored when executing this command.
This command cannot be described before, nor in the middle of, the line number.

NOTE: When the format is inserted midway, the inserted format may not be interpreted correctly. Even if
it is used as a separator HT(09

16) before the comment, it will be skipped. You must use a space (2016).

ECHOBACK

Function Cancel receive code send-back setting

Format ECHOBACK <ON/OFF>

Example ECHOBACK OFF

By assigning ON, data that is received at the communication port will be sent back to its origin divided
into 1 byte each. Cancel the send-back setting by assigning OFF by either running direct input or adding
the line number. The default setting for non-assignment is ON.

NOTE: With the ON setting, the input echo display setting of the terminal application must be canceled
on the host side. When the host side terminal application is not applied, it is recommended to set the
ECHOBACK OFF in order to speed up the process.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 21

TIMER

Function Cancel timer interruption setting

Format TIMER <ON/OFF> [“setting timer”]

Example

By assigning ON, the timer interruption may be set from the time interrupt process. The timer
interruption is assigned by the format of HH:MM:SS within the character string and enclosed with ‘’’’. HH
allows two digit assignment of the hours with a maximum of 24. MM allows two digit assignment of the
minutes with a maximum of 59. SS allows two digit assignment of the seconds with a maximum of 59.

The timer assignment character string can be abbreviated. When it is abbreviated, the time section that
was assigned previously will be applied. Cancel the setting of timer interruption by entering OFF. This
command can be assigned by either running direct input or adding the line number.

TIMER ON “12:15:00”
TIMER OFF

ON TIME$~

Function

Format ON TIME$ GOTO <line number> ON TIME$ GOSUB <line number>

Example

With the assignment of TIMER ON, the preset timer’s progressed time will be detected and proceed
with branch execution. Usage of GOTO or GOSUB which is described after ON TIME$ will be similar to
the usual GOTO and GOSUB.

The return destination of ON TIME$ GOSUB is at the next line of timer match detection line. After timer
interruption of ON TIME$ GOTO, when you want to return back to the operation program, describe the
GOTO in the end of timer interruption.

While running the SEMBL program, timer interruption is detected once and multidrops onto ON TIME$
branch destination, this ON TIME$ branch destination is not inherited from another SEMBL program,
you are required to add a description within the operation program one by one if necessary.

NOTE: When the Calendar chip is not installed, timer interruption will not occur in the preset timer
depending on TIMER ON. Detection of setting timer that has progressed has to be executed before
running the next line. Hence, detection will not be running during SLEEP, do it only after ended SLEEP.

Detect timer interruption when running SEMBL program, jump to the assigned
branch instruction.

10 TIMER ON “10:30:00”
20 ON TIME$ GOSUB 100

10 OPEN “PO1” AS #1
20 FOR I=1 TO 8
30 INBYTE #1, INB$
40 PRINT ASC(INB$);”,”;

Example

Inclusive of the received byte that is ignored at INPUT, data will be read from the received buffer.

NOTE: INBYTE operates effectively only when data is sent to an open port: “PO1” and “PO2”. INBYTE
will behave unstably when INBYTE sends data to an open port other than “PO1” and “PO2”.

50 NEXT I
60 END

BEEP

Function Printer built-in bzzer beeps.

Format BEEP [<tone>]

BEEP ... 1 short beep
BEEP 0 ... 1 short beep

Example

Short beeps last for 175 milliseconds and long beeps last for 400 millisecond. Interval of the continuous
beep (tone 2, 3, 4) is 5 millisecond or longer. This command can be assigned by either running direct
input or adding the line number. BEEP and BEEP 0 has the same behavior.

NOTE: When the buzzer beeps, the BASIC application is in suspension.

BEEP 1 ... 1 long beep
BEEP 2 ... 2 consecutive short beep
BEEP 3 ... 2 consecutive long beep
BEEP 4 ... 3 consecutive long beep

CANCTRL

Function Set cancel code (0316) into enable/disable.

Format CANCTRL <ON/OFF>

Example CANCTRL ON

In cancel code ETX(0316) which is sent from the host, valid or invalid will be set with the assignment of
ON/OFF. Once cancel code is received during RUN from the CANCTRL ON, BREAK the execution of
BASIC program. From CANCTRL OFF, even if the cancel code is received during RUN, it will be read as
an invalid code. This command can be assigned by either running direct input or adding the line number.
The default setting is CANCTRL OFF (cancel invalid) for non-assignment.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 23

GETSTATUS

Function Obtain printer’s status information.

Format GETSTATUS <character variable$>

10 DECLARE STRING STS$
20 GETSTATUS STS$

Example

Send the printer’s status information in accordance with currently established interface protocol. The
printer’s status information conforms to the format of ENQ respond data. When interface is setting at
serial is Ready/Busy or XON/XOFF, the interface will create the status information at format of
STATUS4 expediently.

For details of ENQ respond information format, you can refer to that item of each interface in the SBPL
Programin Guide.

30 PRINT “Printer Status :”;STS$
>RUN
result: Printer Status : A000000 .. when interface protocol is at STATUS4, no
error online standby to receive data.

CTIME

Function Obtain progress time from system lock.

Format CTIME

10 PRINT CTIME

Example

SEMBL operation time is notified by multiplying the count of the printer’s system clock. The recall value
range is 0 - 2147483647(H’7FFFFFFF). If the clock count exceeds the upper limit, it will return to 0 and
is applicable regardless of whether the calendar chip is installed. To convert the clock counter into units
of seconds, remember that 1 count=5 millisecond.

The clock count is initialized depending on the migration of SEMBL MODE and the system’s clock timer
setting command of CTIMER.

>RUN
result: 328790

CTIMER

Function Cancel system lock timer setting.

Format CTIMER <ON/OFF> [<clock count value>]

Example

By assigning ON, the clock count value that disrupts clock interruption is set when the current
progressed clock count is initialized into 0. 0 - 2147483647(H’7FFFFFFF) is given for interrupt timer.

The progressed clock counter value can be abbreviated. When it is abbreviated, the clock count value
that was assigned previously will be applied. By assigning OFF, the setting of the progressed clock
interruption is cancelled.

This command can be assigned by either running direct input or adding the line number.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 24

CTIMER ON 6000
CTIMER OFF

ON CTIME

Function

Format

Example

By assigning CTIMER ON, the progression of the pre-set clock count is detected and proceeds with
branch execution. The usage of GOTO or GOSUB is described after the ON CTIME is similar to the
usual GOTO and GOSUB. The return destination of ON CTIME GOSUB will be the next line of the
progressed clock detection line.

After the progressed clock interruption has used the ON CTIME GOTO and you want to return to the
operation program, the description of GOTO must be added to the end of the interruption.

When running the SEMBL program, once the interruption clock is detected and multidrops to the ON
CTIME branch destination, the ON CTIME setting will be cleared. To continuously operate this
progressed clock interruption, assign ON CTIME again. The assignment of the ON CTIME branch
destination is not inherited from another SEMBL program, you must describe it in the operation program
ono by one if necessary.

NOTE: The progressed clock interruption will happen regardless of whether the calendar chip is
installed or not. Detection of the progressed clock is executed before running the next line. Thusly, start
the detection only after completing SLEEP but not during SLEEP.

Detect progressed clock interruption when running SEMBL program, jump to the
assigned branch instruction.

INARRAY

Function Substitute the input data of byte array into the array variable.

Format INARRAY [<#channel>,] <array variable>, <input digit no.>

10 DIM ARY(8) AS INTEGER
20 Open “PO1” AS #1
30 INARRAY #1,ARY(1),8
40 FOR I=1 TO 8

Example

The receive buffer reads the assigned byte size input data and stores it into the array variable in 1 byte
increments. The array variable is handed over as a command and storage start member must be
assigned. The storage start member can be assigned also for first non-member.

NOTE: INBYTE operates effectively only when printing to the open port of “PO1” and “PO2”. When
printed to an open port except “PO1” and “PO2”, the behavior is unstable. If the assigned variable does
not belong to the array variable, the command will become an error. If the assigned digit is larger than
the declaration of array variable, INARRAY implicitly extends to the maximum size of the array and then
stores the received data.

INUNTIL

Function

Substitute the input data of byte array into the array variable until obtaining the end
code.

Format INUNTIL [<#channel>,] <array variable>, <input digit no.>, <end code>

10 DIM ARY(10) AS INTEGER

result: 65,66,67,68,69,70,72,73,74,75,76,77,0, ...when sending ABCDEF
GHIJKL<NUL>from HOSTPC to the printer.

The receive buffer reads the input data containing the assigned end code and stores the data into an
array variable in 1 byte increments. This command operates after initializing all array elements by the
end code before receiving data. The array variable is provided as a command requiring the storage start
number to be assigned. The storage start number can also be assigned for the non-first number.

NOTE: INUNTIL operates effectively only when printing to the open port of “PO1” and “PO2”. When
printed to open port except “PO1” and “PO2”, the behavior is unstable. If the assigned variable does not
belong to an array variable, the command will become an error. If the receive digit is larger than the
declaration of an array variable, INUNTIL implicitly extends the array number to the assigned input digit
and then stores the received data.

Even if the receive byte size exceeds the assigned input size, the end code cannot be obtained and the
command will be ended. If the data is received, INUNTIL must be printed again. You can judge whether
to reprint INUNTIL or not by checking the array end member to determine if it is the end code.

Fomula: key input value.trigger value x 1024.shift key value.

The shift key value shows values of all keys that can be pressed simultaneously. When two or more
keys are pressed simultaneously, the key input value will be the add-up sum (OR) of the shift key value.
Hence, th actual value of the shift key to be obtained when pressing two or more keys simultaneously,
will be displayed in the total sum value of each pressed shift key.

Example: press ENTER while pressing LINE.FUNCTION.DOWN simultaneously and the key input value
. ENTER(3) x 1024 . (LINE(2) . FUNCTION(256) . DOWN(128) . 3072 . 386 . 3458

The shift key value is calculated from 10 bits of the lower bit (inside of 2 bytes) in which one (1) bit each
is allocated so that it allows multiple keys to be pressed at the same time. To remove only the trigger
value, divide the key value by 1024 and obtain the quotient.

The trigger and shift keys are not allowed for simultaneous input if the keys are the same. Among nine
(9) keys, they cannot entirely be shift keys.

FUNCTIONALITY

There are three ways to enter the SEMBL Mode:

• send SEMBL migration command

• SEMBL selection by LCD menu

• preset the SEMBL auto-run feature.

Once the migration to the SEMBL Mode is complete, the printer will generate the character string
of “WELCOME!<CR><LF>” to the standard output.

SEND MIGRATION COMMAND OF SEMBL

In the Online Mode, send the SBPL command of SEMBL migration. The printer will immediately
migrate from the online mode to SEMBL Mode so the text will executed. The following is an
example of the send data: ESC A ESC C I ESC Z

CAUTION

Do not confuse the ESC C I with other SBPL commands. Do not describe
SEMBL text after the above mentioned SBPL data. When shifting from online
to SEMBL mode, clear the receive buffer once. SEMBL text that is sent
continuously cannot be secured. Send SEMBL text following mode migration.

By giving a program a name that is stored as a parameter in the ESC C I, the program will run
automatically. Details may be found in the “Auto Run of BASIC Program” chapter that follows.

SEMBL SELECTION BY LCD MENU

The following procedure provides instruction on how to shift to the SEMBL Mode by use of the
LCD menu without dependence on the transmission of the SEMBL migration command. Details
may be found in the “Auto Run of BASIC Program” chapter that follows.

1. Press the LINE key to take the printer offline.

2. Press the ENTER key to display the Mode Select screen.

3. Select the SEMBL MODE icon.

4. Press the ENTER key to access the START PROGRAM select screen.

5. Select NONE and then press ENTER to enter the SEMBL Mode.

PRESET SEMBL AUTO-EXECUTION

By setting the SEMBL auto run feature in the Advanced Mode, the printer can operate in SEMBL
Mode automatically when powering on. Details may be found in the “Auto Run of BASIC
Program” chapter that follows.

1. Press the LINE key to take the printer offline.

2. Press the ENTER key to display the Mode Select screen.

3. Select the ADVANCED MODE icon.

4. Press the ENTER key several times to access the SEMBL MODE AUTO START screen.

5. Select NONE and then press ENTER key to power on in the SEMBL Mode thereafter.

AUTO EXECUTION OF BASIC PROGRAM

There are two methods to run the BASIC program which is registered in the printer:

• Auto run when shifting to SEMBL Mode,

• Auto run when inputting power.

AUTO RUN WHEN SHIFTING TO SEMBL MODE

There are two ways to initiate this activity:

• using SEMBL Mode shifting command,

• select SEMBL MODE from the LCD menu.

(1)

USING SEMBL MODE SHIFTING COMMAND

As the parameter of SBPL command of the SEMBL Mode shifting, the registered program name
is handed over. Example: ESC CI , PROGRAM1.BAS

Read the same name of the BASIC program file from the extended memory cartridge and then
allow it to auto RUN.

After the PROGRAM FINISHED execution, it remains with the SEMBL Mode. The READ
PROGRAM LIST will not disappear.

(2)

SELECT SEMBL MODE FROM THE LCD MENU

Use the up and down keys to select the terget program name and press the ENTER key in the
START PROGRAM select screen (refer to previous).

Read the same name in the BASIC program file from the extended memory cartridge and then let
it auto RUN. After the program is finishes execution, it remains with the SEMBL Mode. The
READ PROGRAM list will not disappear.

AUTO RUN WHEN INPUTTING POWER

Use the up and down keys to select the target program name and press th ENTER key in the
SEMBL MODE AUTO START screen (refer to previous).

When powering on again, read the same name BASIC program file from the extended memory
cartridge while starting the printer with SEMBL Mode, and then allow it to RUN. After the program
finishes execution, it remains with the SEMBL Mode. The READ PROGRAM list will not
disappear.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 35

EXITING FROM THE SEMBL MODE

There are four methods of shifting from SEMBL Mode to usual mode (online mode):

• Send SBPL shift command,

• select other than SEMBL MODE from the LCD menu,

• power on/off,

• other SEMBL Mode exit conditions.

Neither of the stored BASIC programs will be cancelled. Once exited from the SEMBL Mode is
entered, the printer will generate a character string of “GOODBYE.<CR><LF>” to the standard
output.

SEND SEMBL SHIFT COMMAND

Send th direct command SBPL to th printer with the SEMBL Mode. The printer will immediately
shift from SEMBL to Online mode enabling the process of SBPL text.

NOTE

SBPL command is not allowed with execution that applies to the line number.

Do not describe the SBPL text after the SBPL command.

When shifting is made from SEMBL to Online Mode, clear the received buffer
once. Otherwise the SEMBL text is sent continuously and cannot be secured.

Send the SEMBL text after confirming the mode migration.

SELECT OTHER THAN SEMBL FROM LCD

Once the printer is shifted from the SEMBL Mode to another mode, it is BO from the SEMBL
Mode. In other words, it is not only shifting to the Online Mode, but also meaning that when the
printer enters into each mode, the related SEMBL Mode has come to an end.

1. Press the LINE key to take the printer offline.

2. Press the ENTER key to display the Mode Select screen.

3. Select the SEMBL Mode icon and press the ENTER key.

4. For the Online Mode, the printer automatically goes online. For all other modes,
enter the password to shift. Once the password is canceled, return to the SEMBL
Mode is possible.

POWER ON/OFF

Power off the printer and then restore the power to restart in the Noline Mode providing that the
SEMBL Auto Run setting is NO within the Advanced Mode.

OTHER SEMBL MODE EXIT CONDITIONS

The printer is able to exit from the SEMBL Mode unconditionally when YES is selected at the
CANCEL PRINT JOB and ENTER is pressed - the printer will shift to the Online Mode. This does
not apply to the POWER ON/OFF condition.

SATO GT4xxe SEMBL User Guide PN 9001148A Page 36

BASIC OPERATION OF SEMBL MODE

SEMBL allows the data processing function to operate as a BASIC Interpreter. Therefore,
registration to the extended memory cartridge from the BASIC program download and the BASIC
debug operation are carried out in the interactive mode.

Below is an example of how to carry out ths operation in the interactive mode with the printer in
SEMBL mode using the Hyperterminal application for Windows.

FILE PREPARATION TO SEND

Hyperterminal cannot edit the optional transmission text on the application. Hence, to run a
relatively heavy operation program, it is recommended that BASIC text transmission be created
by a separated editor and then prepare it as a file in advance. Example:

Operation Program File

10 REM Program 1
20 DECLARE STRING s$
30 S$ = “SATO PRINTER”
40 OPEN #1: NAME “SPL”
50 PRINT #1: CHR$(27);”A”
60 PRINT #1: CHR$(27);”X22,”;S$;
70 PRINT #1: CHR$(27);”Z”;
80 END

A direct command and a single basic program can be sent by inputting them on the terminal
screen of the Hyperterminal according to the prompt (“>”) returned by the printer.

HYPERTHERMAL SETTINGS

Hyperthermal can connect with the communication either with serial line or Windows SOCKET.
The following example explains the process of connecting to COM1:

• Connection Method Directly to COM1

• Emulation Auto Detect

• Telnet Terminal ID ANSI

• Buffer Line Number 500

• ASCII Setting When sending data, local echo OFF, add ON to
the line feed character at the end of the line.

The following is the property screen for setting file SBI.ht based on the above criteria for
Hyperterminal in the Windows 98 platform.

Use the ECHOBACK ON (default) on the SEMBL side for this scenario.

Screen Sequence for Setting Hyperterminal

HYPERTERMINAL OPERATION

Send the previously prepared BASIC text file through the transfer menu .send text file. . This is
done by programming the registration through the transmission of the Operation Program file,
checking the operation from the RUN command direct input, and saving the registration program
from the STORE command direct input.

Once pressing the CTRL key and C simultaneously, CTRL-C control code (03

16) will be sent to

the printer. By pasting on edit menu/copy on the host side, the text area that is selected on the
terminal screen can be copied/pasted.

RPUTY FILE TRANSMISSION

Files that use RpUty can be transferred without depending on Hyperterminal. However, in ordere
to throw away the text sent from the printer, status check of the SEMBL can only be done by LCD
display with ECHO ON.

REPEATING EXECUTION

There are two ways that this may be perfromed: forming a repeating loop in the BASIC operation
program or combining SEMBL auto run with the SBPL command. The following displays the
SBPL data send:

REMARKS FOR SEMBL OPERATION

SEMBL always generates a prompt to print the output data and the status information data of
operational standard output. The standard ouput of SEMBL is allocated in the data port.

Therefore, it combines the status notification data of ENQ and SOH responses and sends to the
data port connection a signal that the host’s status monitor might not be properly working.

To carry out the host’s status monitoring while operating in SEMBL, the sub-port is only allowed
to be used for status monitoring. Thusly, the sub-port can no longer be used for external device
connection.
