Sample
Log-On
This
sample session will
use
an example
to show
you
how
to use the Terminal
Communications
Mode of the
Deluxe
RS-232 Program Pak.
During the
sample session,
you
will
be
shown
how to make selections from
the Deluxe RS-232
Program Pak
Setting
Menu and how
to contact a host once
you
have
selected your
settings.
Let's
suppose that
you
are using
a
Modem II
(automatic dialing) and
you want
to contact a host that
uses
the following
settings:
300 Baud Rate
Full-Duplex
8-Bit Word Length
No Parity
1 Stop Bit
Auto Line
Feed On
Upper and Lowercase
To
establish communications with
this host,
you
would
need to:
1
.
Power-up the
System. Be sure all peripherals
are properly
connected.
2. Type EXEC &HC000
(ENTER) or EXEC 49152
(HUE)
to display the Protocol
Menu.
3.
When the Protocol Menu
appears, compare the default
settings
(those shown on
the initial Protocol Menu)
with
those required
by
the
host.
4. The only
settings for the host that
need to be changed are:
Duplex
Word Length
Upper and Lowercase
Modem Type
5. To change these
settings:
•
Press
(B)
to change the Duplex
setting to Full-Duplex.
•
Press
QD
to change the
Uppercase setting to Upper
and Lowercase.
•
Press
(M)
to
change
the modem setting
to Modem II. Then,
type the telephone
number and press
(ENTER] .
6.
Set the modem to ON and
AUTO/ORIG.
7. Press
(BREAK) . The number
will be automatically dialed.

*Note:
The
RS-232
Break is an interrupt and its use depends on the host
system.
The
heart of the Deluxe RS-232
Program Pak is
the Synertek 6551 ASCI.
It has an on-chip
baud rate genera-
tor, programmable interrupts
and status register
for ease of operation,
false start bit detection,
and echo
mode.
This ASCI
board is memory mapped
to addresses FF68
to FF6B (Hex).
The
6551 uses 4 memory addresses for
the following functions:
Address
Write
Read
FF68
FF69
FF6A
FF6B
Transmit
Data
Register
Soft Reset
Receiver
Data
Register
Status Register
Command
Register
Control
Register
This table
shows that only
the Command and Control registers are bidirectional.
The Soft Reset operation
clears the
6551 internal registers
but does not cause any data transfer. Therefore, the
data
written
is a "don't
care." A
RES* from the
bus
will
clear all registers in the
6551 ,
while
a Soft Reset will only disable interrupts
and transmitter,
turn off the echo mode, and clear the Overrun
Error flag.
The following
shows the Status, Command,
and
Control
Registers and gives programming examples for
each:
