Not true!

It is apparently not well known that the sound card "soft TNC" is only one 
small part of AGWpe.    It is also a serial port manager that can address up to 
16 physical or virtual com ports from hardware or software KISS TNCs 

It behaves something like an logical Ethernet switch (or for you analog types, 
something like a distribution amp for serial data) sharing TNC data with 
multiple applications simultaneously.

AGWpe maps individual data streams from single- or dual-port TNCs to logical 
IP-based ports that can then be shared with as many TNC-using packet or APRS 
applications simultaneously as desired.   It can even split the multiple data 
streams on dual-port TNCs like KAMs coming in on one physical port, into 
separate logical streams.

Properly-implemented AGWpe clients have a "port mask" dialog where you select 
which of the up to 16 logical ports the app should respond to.

At times, I have had APRS Plus, UIview, APRSpoint, UI-Instant Messenger, 
UI-Events and UI-Instant messenger all running off a single dual-port TNC 

The API for AGWpe is documented and available to developers.  The starting 
point is here:
