I have a feeling that it may be some subtle difference with the way vCOM handles the lines like RTS/CTS and DSR/DTR that may be causing problems with certain third party applications. Or it may be that the serial port access code in PowerSDR (which I wrote) is expecting some timing of those signals a slightly different way than vCOM provides. When/if PowerSDR is rewritten for .NET 2.0, it will be interesting to see if the problems persist because .NET 2.0 has its own System.IO.Serial? support.
