1200 bps is 120 characters per second. Thus the time it takes for the

I believe the NIST hardware expects echo to be enabled and expects the
transmit and receive delays to be the same. In that case it adjusts the
timing of the OTM (on-time mark) so that when the OTM changes from * to
# the timing of that OTM compensates for the delay correction. At
least, that used to be the case.

Yes, there will still be limits to this technology, but it's not as bad
as one might originally think.
The remote side starts with 45ms offset - try time1 .045.
Try also remove minpoll, add iburst and burst, change maxpoll to 16.
