one thing I distinctly remember is that when simultaneous two-way Zmodem transfers came out replacing Ymodem, it absolutely blew my mind
(previously all transfers, Xmodem/Ymodem, were one-way with CRC checks on each block slowing things down)
- bluGill 5mo agoYmodem-g (I think I remember that correctly) was faster than Zmodem - but if the CRC failed it aborted the whole send. Often I was willing to take the risk. (at 300 baud that adds up)
- kylemaxwell 5mo agoMy 8th-grade science project was doing a "statistical" analysis of X/Y/Zmodem transfers (and Kermit, I think?). It did well enough to get me to the county science fair here in Dallas, at least. And yeah, Zmodem was mind-blowing for us.
- iberator 5mo agozmodem/xmodem can still be used over ssh :) kermit is actually still in development. I used it in like 2021 to transfer some data over serial from some really old laptop (386sx). Was faster than txp/ip over plip/slip
