I remember using this to transfer files with BBS... zmodem was more popular but kermit could take advantage of full duplex so you could upload some files while downloading others at the same time. I had no idea it was still a thing.
I once had a chat on Compuserve with Ward Christensen, the inventor of xmodem. He seemed surprised that anyone recognized his name.
Kermit is, though, more than that. One example is that it includes a scripting functionality somewhat like the once popular "Expect" package[1]. For things like interacting with a Cisco router cli, ftp servers, etc. Or, as the article mentions, "server mode[2]"...something zmodem also doesn't do.
So, for example, it was really useful "back in the day" for things like connecting to a network enabled modem bank and running batch jobs to do various things.
"Although ZModem came out a few years before Kermit had its performance optimizations, by about 1993 Kermit was on par or faster than ZModem."
But most Kermit protocols in terminal software implemented only the most basic version of the protocol and didn't support all the options that you needed to set.
Not sure about resuming, which was AFAICT only a ZModem thing (and the best part of it).
I also remember using Kermit for a BBS file transfer once. Once.
Similar memory here. Wasn’t sure about the different protocols offered in Telix and I used Kermit once because the BBS offered it. Right after the sysop burst in on chat and told me not to use Kermit and only use zmodem.
That was basically what I did until HSLink came out and let me do bidirectional, chat, and play Tetris while waiting. Good times. Good memories.
