I believe you'll find answers in the "Files" section for this group.
See "897nomic.zip" by K8YSV. The document refers specifically to the
Rigblaster nomic, but I think the information would be useful for
connecting any PSK31 interface.
You asked why one would need the squelch status line. The squelch
status line is needed by TNC's such as the AEA PK-232. It's there to
prevent a TNC from transmitting when there is a signal strong enough
to open the squelch. Unlike, say, FM packet, PSK31 interfaces needn't
care about the squelch status. With PSK31, there may be many signals
in the pass band that would keep the squelch open. It's up to the
PSK31 operator to put a narrow signal into the right place in a wider
In any case, the FT-897 data port works nicely both for TNC's or for
sound card interfaces such as the Rigblaster Nomic.
