PCI 4833 RS485 baudrate does not support nonstandard baudrate

[GaryZ21]

I have a PCI 4833-4 rs485 card, using CVI.  I can't configure the com ports to non-standard baud rate.  I have upgraded the serial software to 3.0 and still haven't gotton any luck.  What can I do to fix this problem?  I have the card installed in a IBM machine running XP.

Hi GaryZ21,

Exactly what behavior are you seeing?  Are you receiving an error when you try setting a non-standard baud rate, or is something else indicating to you that it is not working?  Are you using the RS-232 library, or NI-VISA to communicate with the COM Port?  Please include a code snippet to show how you are attempting to configure the serial port, so that we can identify any problems which may be present.
