Re: Another ProTERM 3.1 Patch - Request for Testers

[Hugh Hood <hughhood@earthlink.net>]

Here's a little update on the progress of the ProTERM 3.1 patches for both
the IIGS built-in (Zilog SCC) serial ports at 115,200 baud and the Super
Serial Card (65C51 ACIA Chip) at 115,200 baud.

Remember that there are differences in the disk patch locations depending
upon whether the 11 MAY 93 or the 05 JUL 98 assembled version of ProTERM 3.1
is used. Currently, the 11 MAY 93 version is on the Lost Classics Project
web site, and many have already downloaded it.

The good news is that, after examining both versions, I've determined that
the _memory_ load locations for the applicable patch code for the 115,200
baud routines are the same, regardless of the assembly date of the code.

Hence, while the disk patch locations may vary, we can direct our patches at
the specific memory locations that will not vary. That is why I've decided
only to distribute these patches as ProTERM 3.1 Macro Files that will work
with any ProTERM 3.1, regardless of assembly date. These macros will patch
in memory, and will eliminate any requirement for keeping a separate copy of
ProTERM on your hard drive. Also, they will be reversible via macro.

But, I _still_ need someone to confirm that my patch for the Super Serial
Card at 115,200 baud works.

So, for those with the freeware ProTERM 3.1 downloaded from the Lost
Classics Project website (Assembled 11 MAY 93) ...

ON A BACKUP COPY, fire up your block editor (e.g. ProSel's Block Warden) and
follow the file PT3.CODE 0 to Block 12, Byte $168A and change the value
there from $03 to $00.

Save it back to disk, run ProTERM 3.1, set it for 110 baud and let me know
if it can communicate at 115,200 baud. Of course your connected computer
must also be capable and set up for this rate prior to the test.

Thanks, and I apologize again for the confusion I caused with the multiple
ProTERM 3.1 assembly dates.

I would emphasize that, at this speed (115,200 baud), an accelerated machine
is probably necessary, as well as a hardware handshaking RTS/CTS cable, and
the latter day 65C51 chip in the Super Serial Card.
