Hi Henrik!
There is just something very basic I seem to be missing somewhere. Yes, the MAX232 circuit is good and has been working for a very long time. I can go into Microcode Studios, open the comm screen, jumper the Rx to the Tx on the MAX232 output, connect, type something in and it returns! Yes I have been using the ICD compile. I just wish the IDC error message was more exact! Best, Ed
