Trying to connect WiModem to Ubiquity AP-LR

You are in C64 mode, right?  

Yes of course.      Striketerm loads ok.  The default "userport" modem setting works at 2400 baud and with Wibridge.  When I select a different modem type different things happen but all lead to the machine locking up.  I downloaded Desterm 3.02 (C128 mode)  it supports Zmodem and 9600 baud but I just get errors when transferring files, eventually the file transfer aborts.
