[comp.os.cpm] QTERM patches

In article <220@rick.att.com> ahm@rick.UUCP (Andy Meyer) sez:
> Before QTERM will run on a specific machine, however, it needs to be

One word of warning (from the author :-) ). The patches in QTPATCH.LBR
are for V4.1, and may not work with V4.2. The change to make them work
is relatively small, towards the bottom of the patch is a patch area
for putting things like initialisation code in. In V4.1 it starts at
0x0276, and runs to 0x02ff. In V4.2 it got shifted to 0x0280. What
this means is that if you see a line:

.org	0x0276

in the patch from QTPATCH, followed by a bunch of code that does things
like setup, clearing up, or handling baud rate code that's too big to fit
in the 16 byts allocated, then change that from 0x0276 to 0x0280.

I will be releasing QTPAT42.LBR in the (fairly) near future, but there's
one thing left to take care of before I can set to and get all the
patches I have corrected for use with V4.2.
