xmodem?

[KenHorse]

Yea I know it's an old protocol but still...

Anyone figure out how to do it in PHP? Searching the forum turns up nothing xmodem related

What on Earth would you want to use PHP with XModem for?

Anyway, the specification is 3/4 of a page. https://web.mit.edu/6.115/www/amulet/xmodem.htm

I think the best solution will be just execute shell command to use any existing command line application fir xmodem. You can handle the response as you want in php, but it will be good only if you need some logic for that and you know only php. If logic isn't needed you can just write all commands in .bat file or learn another language that will be better for this purpose.
