I can successfully execute an XModem file transfer between a PC running a LabWindows application an a standalone PC at 9600 Baud. If I increase the baud rate on both machines above 9600 baud, other serial transfers still work, (ComRd, ComWrt) but XModem transfers time out. Any suggestions?
Have you tried running NI-Spy to capture what is happening when the code is running? Also - try increasing your timeout, you may not be giving the instrument enough time to respond.
Please let me know if you have any other questions,
