2X9600 MODEM/UNIX OR XENIX HOSTS
|
|||
|
|
|
|||
|
|
|
|||
|
|
The following configuration has proven effective for 9600 baud
|
|||
|
|
communication with UNIX/XENIX hosts.
|
|||
|
|
|
|||
|
|
Switch settings for 2x9600 modem:
|
|||
|
|
|
|||
|
|
- Front : switches 2, 3, and 8 down
|
|||
|
|
- Rear : switches 2, 3, 5, and 7 down
|
|||
|
|
|
|||
|
|
An initialization string needs to be sent to the modem on the
|
|||
|
|
host side and to the modem on the terminal (PC) side. This can
|
|||
|
|
be handled by creating a file ('hostinit' in the example below)
|
|||
|
|
and using the 'cat' command in a shell script to initialize the
|
|||
|
|
modem.
|
|||
|
|
|
|||
|
|
Host initialization string:
|
|||
|
|
|
|||
|
|
ATE0Q1S0=1&C1&D2\N3\Q3\J0
|
|||
|
|
|
|||
|
|
Example of using the 'cat' command with SCO XENIX v2.0
|
|||
|
|
or above:
|
|||
|
|
|
|||
|
|
cat hostinit > /dev/tty7b
|
|||
|
|
|
|||
|
|
In the above example, 'cat' causes this initialization string
|
|||
|
|
to be sent to the 'tty7b' terminal port on the host. An
|
|||
|
|
initialization string must also be sent from the terminal to
|
|||
|
|
the terminal's modem.
|
|||
|
|
|
|||
|
|
Terminal modem initialization string:
|
|||
|
|
|
|||
|
|
ATE1Q0X4&C1&D2\N3\Q3\J0
|
|||
|
|
|
|||
|
|
After the terminal's modem is initialized, standard HAYES 'AT'
|
|||
|
|
commands can be used, such as 'ATDT' for tone-dialing.
|
|||
|
|
d:
|
|||
|
|
|
|||
|
|
"grep AST /etc/serinit"
