Re:   MODEM working!!


I managed to get the thing working, using the CPM system calls from PLINK,
as I mentioned earlier.  The problem with the bad sectors was that my
subroutine to read a character stripped the parity bit, thus providing
a guarenteed wrong header/checksum.

It is a bit of a kluge, but it works.  I used conditionals around all
of the system calls to any MODCTLP, MODDATP, or MOD---- sympols, using
IF TRS  and IF NOT TRS, so that it may still be assembled for other things.

As soon as I get a chance to xfer it over to the PDP-10, I'll let you or
anyone else who might be interested know.
