I am trying to write a program for my Tandy 1400LT that will switch between the modem and the com port (for some reason you can't use both at the same time). I have the technical reference manual and it says to do that it is &0FCH bit number 4. I have tried to change that bit using BASIC and PASCAL with no luck. Can anybody out there help me???
