[nos-bbs] Setting up JNOS with a KPC-3 modem

[debiani386]

This worked! I am now able to connect to other stations with JNOS using the KPC-3.

A new entry for my notebook ;)

Notice we are using a USB version of the KPC3P which mounts as ttyUSB1 on our system.

The problem I am running in to when connecting to any station is that jnos will connect to the station, but not display any text. It does this no matter what station I connect to.
