Thanks for the replies on the 232 monitor, I came up with another idea, can anyone tell me if it will work? First of all, the two machines will not be talking at the same time. I have given some thought to connecting both lines to a MAX233 on pins 4 and 19 ( R inputs ) then connecting the R outputs to a 2-input OR gate, and the output of it back to one of the ( T inputs (pin2)), then my monitor computer to the ( T output (pin5)) of the max233. Will this work? I have never used a max 233 do they require any caps/ wierd voltages? Can they get power from the 232 port? Thanks, geb1@isis.msstate.edu
