Jerry,

Do not know why xasrit.org is down but you can still get it from Sourceforge.net at 
<http://sourceforge.net/project/showfiles.php?group_id=45562&package_id=38231&release_id=620057>

As you know I use UI-View here.  I run the KPC-3+ in TERM mode.  I added the line "INT TERM" as the first item after 
[INIT_COMMANDS] in file Peak Systems\UI-View32\CMDKTRONICS.CMD.  In comms Setup TNC TYPE is KTRONICS and Host mode is 
none.  This way the TNC does all the digi functions.
