Trouble communicating with SR865A LabVIEW driver using RS 232 serial port
Using NI MAX I ensured that it is communicating using RS 232 (using command *IDN?\n  no error is found), but when I run the lab view program in block code at VISA open Error -1073807346 is showing any lab view support will be appreciated.

Well that error usually means something already has the VISA resource open. (Another program, The VISA Test Panel in NI-Max, etc)

Also since you seem new to LabVIEW serial communications, I suggest you watch this video: VIWeek 2020/Proper way to communicate over serial

Typically for Stanford Research you had to specify the communication bus with the command OUTX, if I remember correctly, OUTX1 was GPIB, OUTX0 was serial, but look that up in the manual. This should be done at the beginning of the program.

Hi, Did you find the solution?
