[aprssig] Alinco DR-135T - EJ41U internal modem

[hasan schiers]

Besides the fact, that once in KISS mode it doesn't work reliably. It is a 
total FAILURE as a KISS tnc. Nice radio, useless tnc when most of the nice 
aprs clients do their best in KISS mode, not to mention AGWPE, which gives 
multiple applications access to the same radio, IF and ONLY IF, it works 
properly in KISS (which it doesn't).

The D700 will work in KISS mode...I use it for PCSAT2 as one of 3 agwpe 
ports (ui-view on 144.39 and ISS on 145.800). The D7 will NOT work 
(reliably) in KISS mode, either.

We seem to go through this same conversation every year or so, when some 
unsuspecting soul gets "snookered" by non KISS supporting hardware.

The problem is that all three radios respond to the KISS ON parm, but may or 
may not support this mode properly, which leads to a lot of confusion, and 
not a little disappointment.
