I checked the telnetd sources yesterday and they indeed do all escaping for
me. But there may be other minor things on mbsebbs side too that doesn't
affect all programs. I made some changes to the tty raw mode and it seems to
work "better" now, ie. some blocks are transferred now and syncterm aborts
sooner, now not on timeouts but with too much errors. I haven't checked the
details yet, it was too late yesterday evening.

Maybe I add the IAC character to the character to escape withing zmodem and
see how that goes.

Ok, I havent tried the last one yet, but I guess it won't make a difference
from this side.

Not at the moment, thanks.
