Downloading problems with WiModem 232 and a UDS-10

And Xmodem is more forgiving so it doesn't error out in the same time period.


Which also probably explains why it works (mostly) fine for people calling in from
outside of my LAN. It only goes from my router to the WiModem 232 on DarkForce
and back, not looped around my LAN.

Thanks Jim.  Smile
