CVI nonstandard rs-232 baud rate

I am trying to use an RS-232 comport using a non-standard baud rate.  Is it possible to send data at 2344 baud.  when the stop bit is received switch to 4800 baud to receive data on the ? From post I have read users indicate the comport driver will interpet this non-standard baud rate.  Will it keep it at 2344 or will it round up/down?

Hi Jon,

 

According to the help document for the OpenComPort function, nonstandard baud rates are accepted. The help file notes that all baud rates are interpreted literally by the driver.
