[aprssig] TNC command formats

I think a hybrid might work.  Define a command that selects the 'current'
port, but override it with the extra parameter like Wes suggested.  That
way, single-port software would still work, and by setting that current port
manually, you could select which port it was controlling.  Just make my
command line parsing a little more complicated.

As for cross-port WideN digipeating, those requests will be Henk's problem.

code, so as new versions become available, they can just be dropped in.

It works pretty well in IOS but typically you're changing a couple of
things at a time. I definitely agree with the / as used in Kantronics has
oddities. (Ask me how many things muck up with my 3 port KPC9612+...)

This works but could get odd for a single port device. You may want to
handle the case where it is optional for a single port device. (Probably
want to permit it though for consistency.)

...and if you do support cross-port digipeating make sure to allow WideN
style digipeating across ports. The 9612+ can't...
