Yes - tried all available ports.? Serial cable (DB9 to RS232 4p4c) is 2 foot long, untwisted pair cable but also unshielded.? The FTDI to USB are all very short too (I have 3 of them, plus now an ATEN version.? Thanks fo the advice - but still perplexed!? Tomorrow I have the morning clear will will try a completely separate PC with just the gemini and pempro software installed....
