xmodem adventures on the RC2014. I'm able to download from the RC2014 to my laptop over TCP/IP, but not the other way around.
That's already more than I expected though!
This is with a patched XMODEM.COM I had to grab from archive.org because the original site went down somewhere between last year and now.
It's using CON: to send/receive bytes. I suspect that upload is not working for the same reason DOWNLOAD.COM is not working, and that is that the ESP8266 is pushing data into the serial port faster than XMODEM.COM on the RC2014 can process.
The other way around, downloading from RC2014 to laptop, the RC2014 sets the pace, not the ESP8266 (apart from what little control data goes from laptop back to RC2014 to acknowledge data) so there's no problem with dropped characters.
