Notes:
1.

For simple AHDLC quoting on the serial port, the raw-mode has to be enabled on both the 102PC-SEs. Raw-mode is disabled by

default

102PC-SE Module-1 is configured for modem dialing. 102PC-SE Module-2 is configured for modem answering.

If you wish to have a complete control on the modem-dialing end, use the chat-scripts. By default the dialing-method is

configuration.

Refer the following commands in the Command Line Section for more details on the chatscripts.

# set serial s0 modem dialing-method ?
# set serial s0 chat-script ?

Important Note:

The chat-script should be used ONLY FOR THE DIALING END.
