This may be a silly question. I did check the manual first.
When two modems are paired this way, does the port speed need to match? I had no problem pairing my 38.4Kbps WiModem232 and WiModem connected at 9600 but, despite everything on the terminal side having the correct/suggested settings, I still immediately got errors during ZModem transfers.
I tried two different terminal programs on the Amiga side, finally settling on NComm. At this time I also realized it would be good idea to match the block size to what is set in StrikeTerm (1024 blocks). Amiga terms typically default to 16k for ZModem. This change was perhaps a Duh! moment. I've never given much thought to it in the past.
I had trouble selecting NComm's built-in Zmodem (it causes a GURU) so I stuck with the external xprz.library. I then set the port speed to 9600 and reestablished NULLMODEM mode.
Finally...I am able to start my upload...but...sigh...still errors.
I then thought...what the heck, let's try changing StrikeTerm's handshaking setting from software back to hardware.
Another transfer was started......hey....no errors! It would seem the hardware handshaking setting *is* correct in StrikeTerm.
Uhh oh.....the transfer made it to approx 60% completed and then I started to see errors on the C64 side.
Well, this is still good. A first for me, actually. I have never seen a ZModem transfer on a C64 go this long without errors.
I will keep testing....
