Disabling UP9600 hack for use with C128
I'm just curious what your suggestion might be then? I have other RS232 interfaces that work fine in 128 mode, under GEOS and Wheels.
Did you cut the other jumpers? If that doesn't work then it would be a problem with the software and the only solution would be to unplug the WiModem. The situations I have seen are when the program accidentally uses the user port lines.
