Thanks for that. Looked online a bit, I’m going to order an rs232 to usb null modem cable. Then it looks like in DOS I should be able to set the baud and just copy a file to the port. On the receiving side I can program something to just read from the com port straight to a file. Add some automation and voila. 🤞

Yeah, sounds like a plan. The zmodem protocol was designed for this if you wanna save writing your own tool from scratch?

  We’ll see how far I get. I mean if I can just do copy file \\.\COM# on the DOS side and cat /dev/USB# > file on my laptop side then I’ll be happy.

    Good luck, let us know your results.
    
    Be sure to check the hash of the files before and after. You could also zip them before transmission for that functionality.
