Karen,
if you are getting changes on CTS then there is some
handshaking trying to happen. Even with CTS handshaking supposedly
disabled. Check that the plug is wired correctly. Especially check
that the instrument is a DCE (data comms equipment), because TxD and
RxD (pin 3 and 2) are reversed in a DTE (data terminal equipment).
I have not used the serial control on Win2K recently (I do Mac only
these days) but the last time I used it (on XP) I had no hassles.
Check that the COM port number is set correctly in RB.
Regards,
Tony Barry
