All NI serial hardware supports standard baud rates. In addition, the
PCI/PXI-843
x
family of hardware supports any baud rate between 2 bit/s
and the maximum supported baud rate for that interface.
National Instruments considers the following baud rates to be standard.
NI serial hardware supports these rates up to the maximum rate
specified. Your device may also support additional baud rates not listed
below:
110
14400
300
19200
600
38400
1200 57600
2400 115200
4800 230400
9600 460800
To set the baud rate, set the VISA Baud attribute or use the Windows
SetCommState function and pass the actual value of the baud rate in the
BaudRate
field of the
DCB
structure.
