Fantastic explanation, thanks! Also nice shout out to Tandy with the CoCo and Tandy 1000. I remember xmodem as well, as well as upgrading to szmodem eventually and playing games while files transferred. :) It's also interesting that xmodem is still useful today, with some terminal programs like "Secure CRT" supporting it as a convenience to upload and download files in place without opening up a separate SCP connection.
Glad you enjoyed it. Actually its funny you mention this.... the inspiration for doing the XMODEM vid was originated based on how I copy files from my Linux box to the Coco which is pretty similar except the transport (pure RS-232 instead of telnet/ssh) is different.
What I nice simple protocol. I shall implement it into my ToE home-brew computer's ROM. Q: I've not seen any new content in a while, are we going to see any more soon?
By the time I got in to BBses Xmodem wouldn't be used if you knew better except on rare occasions where it was the only option available. Usually Zmodem would be used, Maybe on a few BBSes Zmodem might not be available and I would use Ymodem.
Sorry, and thanks for the comments on the previous upload! Unfortunately I realized I had included a picture on the original vid that might have caused licensing issues so I reluctantly had to edit and re-upload.
Just implemented a cut-down version of Xmodem on my 65816 machine (by Mike Billington) and your explanation was the completing piece. 👍
I came across this video while unbricking our cisco switch that only supports xmodem file transfer from Rommon mode (like a safe mode)
Excellent video. Thank you.
Fantastic video.. chronically underviewed!

Awesome, looking forward to Zmodem
Oh that protocol analyzer! Sweet move mate!
Where did you go?
Mikey Term and it's magical multicolor border on the COCO! I remember it well. BBSing rules.
keep it up bro, although I'm younger for this old stuff but I like it.
high quality video!

Try implementing zmodem, it allows for resume.
I have to use xmodem, because the coworker bricked the cisco switch 2960 we use. Booemer protocol painfully slow
thank you!
