1.4 External Computer Components
The following information provides new mechanical changes to the models, which are different
from earlier models
Universal Serial Bus
A Universal Serial Bus (USB) connector has been added to select models on the left side of the
computer. The connector provides an interface for USB peripheral devices.
On models without the USB connector, a plastic insert covers the connector space. The plastic
USB cover is included in spare part 254981-001, the miscellaneous spare parts kit. The kit also
ships with such items as replacement clutch covers, rubber feet, battery spacer door, etc. (See
Chapter 4 in the Maintenance and Service Guide for miscellaneous spare parts.)
Battery Spacer Door
IMPORTANT: The Battery Spacer Door, which is a component of the Dualbay compartment, has
been modified.
The new battery spacer door pushes 1pushes inward with a single motion, as compared to the
previous version 2 which pulled out and pushed inward (
Figure 1-1).
NOTE: The Battery Spacer Door is included in the miscellaneous spare parts kit (spare part
254981-001).

Appendix C
Modem Commands
This section includes modem commands for the 56Kbps internal modem. The telephony modem
is designed to operate with the preinstalled software in the computer. The modem is compatible
with Microsoft Windows 95 (and later) or Windows NT 4.0.
Table C-1
Modem Commands
Command Description
A Answer Command. A instructs the modem to go off-hook and answer an incoming call.
Bn Communication Standard Setting. Bn determines CCIT vs. Bell standard.
0: Selects CCITT V .22 mode when the modem is at 1200bits/s
1: Selects Bell 212A when the modem is at 1200bits/s (default).
2: Unselects V23 reverse channel (same as B3).
3: Unselects V23 reverse channel (same as B2).
15: Selects V.21 when the modem is at 300 bits/s
16: Selects Bell 103J when the modem isat 300 bits/s (default).
Result Codes:
OK n=0, 1, 15, 16
ERROR Otherwise
Cn Carrier Control. The modem will accept the C1 command without error in order to assure
backward compatibility with communications software that issues the C1 command.
However, this modem does not support the C0 command. The C0 command may instruct
some earlier modems (such as the Smartmodem 1200) to not send carrier (ie., it puts them
in a receive-only mode).
0: Transmit carrier always off.
1: Normal transmit carrier switching.
Result Codes:

Table C-1, Modem Commands,
Command Description
Dn Dial Command. Dn instructs the modem to begin the dialing sequence. The dial string (n,
including modifiers and the telephone number) is entered after the ATD command. A dial
string can be up to 40 characters long. Any digit or symbol (0—9, *, #, A, B, C, D) may be
dialed as touch tone digits. Characters such as spaces, hyphens, and parentheses do not
count—they are ignored by the modem and may be included in the dial string to enhance
readability.
The following may be used as dial string modifiers:
L Redials last number. Should be the first character following TD, ignored otherwise.
P Pulse dialing
T Touch-tone dialing (default).
V The modem switches to speakerphone mode and dials the number. An ATH command

Table C-1, Modem Commands,
Command Description
On Return On-line to Data Mode.
0: If the modem is in the on-line command state, the O0 command causes it to go to the
on-line state of the previously established connection. If the modem is off hook in the
idle (off-line command) state, then the O0 command causes it to go to the handshaking
state. Originate or answer mode is determined from the last D or A command, or R dial
modifier that was selected. If the modem is on hook in the idle state, or if the modem is
a test state, then the “ERROR” result code is returned, and no action is taken.
1: If the modem is in the on-line command state, the O1 command causes it to go to the
on-line state of the previously established connection, and retrain its adaptive equalizer
(if applicable). If the modem is off hook in the idle (off-line command) state, then the O1
command causes it to go to the handshaking state. Originate or answer mode is
determined from the last D or A command, or R dial modifier that was selected. If the
modem is on hook in the idle state, or if the modem is a test state, then the “ERROR”
result code is returned, and no action is taken
3: If the modem is in the on-line command state, the O3 command causes it to go to the
on-line state of the previously established connection, and issue a rate re negotiation
sequence (if applicable). If the modem is off hook in the idle (off-line command) state,
then the O3 command causes it to go to the handshaking state. Originate or answer
mode is determined from the last D or A command, or R dial modifier that was selected.
If the modem is on hook in the idle state, or if the modem is a test state, then the
“ERROR” result code is returned, and no action is taken
Also note that as the O command returns the modem to the online state, the protocol,
compression, and connect message (as enabled by the W command and S95) will be
displayed as if the connection was just being made.
P Select Pulse Dialing. P will apply to all subsequent D commands, until altered by the T
command or the T dial modifier. Note that P is both a command and a dial modifier.
Qn Result Code Control. Result codes are informational messages sent from the modem and
displayed on your monitor. Basic result codes are OK, CONNECT, RING, NO CARRIER, and
ERROR. The ATQ command allows the user to turn result codes on or off.
0: Enables modem ot send result codes to the computer (default).
1: Disables modem from sending result codes to the computer.
Sr Select S-register r. Sr is the command to query or write to the selected register.
Sr=n:
Sr?: Select S-register r, read and report its value.
T Select Tone Dialing. T is both a command and a dial modifier. Applies to all subsequent D
commands, until modified by the P command or the P dial modifier. This command
instructs the modem to send DTMF tones while dialing. This is the default setting.
Vn DCE Response Format. Vn controls whether result codes (including call progress and
negotiation progress messages) are displayed as words or their numeric equivalents.
0: Displays result codes as digits.
1: Displays result codes as text (default).
Wn Result Code Option.

FAX Commands
Command Description
+FCLASS=1 Enter FAX Mode. The command AT+FCLASS=1 puts the modem in FAX mode.
+FTS=<n> Transmission Silence. This command causes the modem to stop transmitting data and
pause for 10 * n ms. At the end of this period, the modem then responds OK. You can
specify any number from 0 through 255 as the value of n; for example, a value of 5
specifies a period of 50 ms. This is a FAX command only, responds with the ERROR result
code if in data mode.
+FRS=<n> Receive Silence. This command causes the modem to listen and wait for a 10 * n ms
period of silence on the line. At the end of this period, the modem then responds OK. You
can specify any number from 0 through 255 as the value of n; for example, a value of 5
specifies a period of 50 ms. This is a FAX command only, responds with the ERROR result
code if in data mode.
N=0—255 (10 ms intervals)
+FTM=n FAX data transmit protocol. This command causes the modem to transmit data at the
modulation specified by <n>. This is a FAX command only, reponds with the ERROR result
code if in data mode. The following table shows the values you can enter for this command
and the meaning of those falues.
