Error 1073807298 on VISA write

I also got error 0x4000FFC2 as negative.

I get it in an application to send firmware to TMS320C2000 through RS232. 

The reason is that for each byte I send, I get the same byte in response.

BUT, not the last byte. I get no response from it, which creates this error. So I did as you did, I remove this particular warning.

I can also confirm that setting the buffer size using the VISA Set I/O Buffer VI fixed my problem interfacing with a USB to serial converter.

 

Thanks Jim!
