Hi Boraxman,
In a message to Rixter you wrote:

I've never had a problem with zmodem over TCP. Over the years I've
run some pretty out there config's with virtual pc's, emulation,
various hacks to run x86 on arm etc etc. Also use a really old and broken phone as my internet connection when in the woods and in
umpteen years of doing this I've only ever lost a QWK packet due to
user error never due to zmodem. (Sure sometimes, there are so many
errors in the download that it keeps restarting, but it does
eventually complete!)
One protocol which is good for asynchronous transfer and "sometimes on" connecctions is NNCP. It is based on UUCP, Unix-Unix copy, but incorporates encryption and can be mixed with over-the-wire
transfers and physical transfer
I will check NNCP out though as it sounds interesting.
... Photographers do it with a shutter.
my experience over the past 27+ years of bbsing on the internet is some people have problems with zmodem over tcp, and some dont. I have seen with own eyes when people have problems. myself, i've never had a program. I probably have done more uploads and downloads than most people.

I've found it that way, more specifically, when using syncterm. Not sure of it is the syncterm implementation, but I think lrszrz has also hadYes, but zmodem is a bit flaky over TCP sometimes.
The latest 1.8RC2 of SyncTerm fixed an issue with ZModem.

I thought it wasn't so much TCP, but the fact it's quite often ZModem over Telnet over TCP.

I have had issues with ZModem over SSH over TCP when transferring within my home network, and it was escape sequences. The -e option to escape control characters fixes it.Yes, but zmodem is a bit flaky over TCP sometimes.
I thought it wasn't so much TCP, but the fact it's quite often ZModem over Telnet over TCP.
In which case, there is overlap between ZModem control sequences and Telnet control sequences, and they interfere causing transfers to go whacky.
If the terminal client and board are Telnet-aware, it usually works really well.
The issues grow with "Wifi-232" modems, and Telnet-Fossil bridges, where the sides need to agree on how Telnet control sequences are to be escaped.
