You might try setting the UltraLite CPU speed to SLOW and see if this
helps. I used to get all sorts of errors and hangs running comm
programs with the internal modem that went away when I tried the slower
speed. (Using an external V.32 modem at high speeds was never a problem;
only using the internal modem). Now I just have the comm program set the
CPU speel to slow whenever it detects that I am using the internal modem.
