Question for the crowd, Is there any issue with the signal levels on the TPDD not being truly RS-232, and so it isn't able to signal on the line to the right levels and hence cannot connect to a PC properly?
What I am trying to do, since VirtualT seems to be unable to receive any data (still can't get that to work), I've reverted to this M100 <------> PC COM1 (sniffer program) PC COM2 <------> TPDD I have the M100 <---> COM1 working I have COM2 <-----> NADSbox working But I cannot get COM2 <-----> TPDD working! I have a feeling it is the non-RS-232 signal levels of the TPDD. thx Steve
