Well, what do you know, you *can* revive the old days 😉

#WardChristiansen was one of the unkown pioneers. He, along with his friend Randy Seuss, founding the first computer #BBS in Chicago due to a snowstorm. You can read more about Ward here:

#Ward also created the #XMODEM protocol in 1977. He was interviewed for the fantastic BBS Documentary by @textfiles , and appears in it at various places, starting here: https://youtu.be/Dddbe9OuJLU?feature=shared&t=405

I finally got #syncterm working, and I've been poking around bbs's listed in an old copy of 2600 I had lying around. there aren't that many users, but it's like a fun little scavenger hunt, where the goal is to find more sites to connect to.

But also, how do I download things? do I need a second client?

RIP Ward Christensen, another modest human that shaped our online lives more than we probably realise. https://arstechnica.com/gadgets/2024/10/ward-christensen-bbs-inventor-and-architect-of-our-online-age-dies-at-age-78/ #BBS #XMODEM

Ward Christensen RIP.

Just downloaded an early 1980 XMODEM specification from Bitwoods RBBS-PC using Xmodem over serial console over SSH over IPv4 over LTE network using a 40-year old 8086 just to show that the protocol still works.

RIP Ward Christensen, co-founder of the first computer Bulletin Board System to go online and author of the XMODEM protocol, among other accolades.

so like in 2003 or 2004 i wander past my homies desk and she's got kermit up and i said oh baby did someone say serial console.

we're hanging out shooting the shit w/ a SOC escalation for some CPE not coming up on VPN and it's before we had something @ducksauz would select and imp(!) but there's a small crowd gathering cuz these two weirdos are talking like this is a good time. some syntax haggling and agonizing pastes. if only we had #xmodem instead of uuencoded rpms 😭

A typical #RetroComputing sunday with my #Commodore64 - first, testing #xmodem #CRC #file #transfer to #rc2014bbs and then checking out #QLink (the "reloaded" system). Unfortunately, there aren't that much services active there (anymore?!), except the community boards.

I am currently doing some testing with #rc2014bbs and there is something strange here:

#rcbox #BBS runs on a Z80 CP/M system ( #rc2014 ) and I am using the CP/M file transfer tool KMD.COM to #transfer #files to and from the system via #xmodem (CRC and 1K - both possible).

This seems to work as long as the client machine up- or downloading files is an #8bit machine: a RC2014 with #Qterm works, a #Commodore64 with #CCGMS works - but as soon as I try to use #Syncterm or #Qodem or any other modern #Linux #terminal #program the transfers fail with either "error in header" or, more often, with "CRC error".

How is this possible?! 🤔

Trying - and totally failing - to send files via #xmodem on Linux to a slightly special Z80 machine.

It's a MinZ, a 36 MHz Z180 in a tiny case. It runs CP/M, but uses a dual serial USB interface. It gives me /dev/ttyUSB0 for terminal but /dev/ttyUSB2 for xmodem transfers. It comes with patched xmodem COM files that use this second serial port. But can I get Linux to do anything but immediately disconnect?

I took my time today to rework some of the menus of #rc2014bbs (RC-BOX BBS - the world's first and probably only #rc2014 based #BBS system in the world) and do a little maintenance.

There's a new tool, "FOR", which will list all #files that have recently been #uploaded via #xmodem or #ymodem

There's now also a help file in the default user area, which you can view by entering TYPE HELP.TXT on the CP/M command line.

Up-/and downloads work, but not with modern terminal clients. Use your #8bit hardware and an appropriate #terminal program with #xmodem support to successfully upload files. I have successfully tested xmodem transfers using #StrikeTerm on a Commodore 64.

See my profile for information on how to connect to RC-BOX BBS (the address is listed there)

EDIT: the C64 terminal program I used for the screenshots is "X-Term!"

Auf Linux nutzt man sowas wie #Minicom.
Was gibts vergleichbares bedienbar übers #Terminal (bevorzugt Git-#Bash) unter Windows mit dem zB #XModem gesprochen werden kann? 🤔

@bigzaphod When I started #BBSing in the early #1980s on my #Commodore64 the file transfer protocol choices were #XMODEM and #Punter, the latter largely exclusive to #Commodore #BBSes.

Trivia: XMODEM was invented by Ward Christensen, co-creator of the first #BBS

I have never used the #xmodem in my life, but this is one way to get the waveforms out of my oscilloscope, so now I’ll have to master this one under the #DragonFlyBSD.
