Can I get incoming byte count prior to CNiVisaSession::Read()?

[dahill]

I would like to determine how many bytes have arrived via the COMM port prior to specifying the count in the CNiVisaSession::Read(buffer, count, actual_count)?  This way I could avoid timing out due to an overcount.

you can check the VisaSerialBytesAvailable attribute. It returns an unsigned int 32 value.
