Agree.  In some TNC's if the own-stantion TNC digipeats a
packet, then it does NOT appear to that own-station TNC serial
port unless certain parameters are set just right.

The KPC-3+ is  ideal not only for 5 channels of telemetry, but
also for giving you remote control of up to 4 separate on/off
circuits.  So you can monitor the temperature and then any time
you want, logon remotely with the pasword protected remote sysop
mode and turn the switches on and off.

We use these TNC's all the time for telemery command and control
this way.  See our mods (about half way down this page):
