Patch list for CATMSFT and CATPCPI CP/M Apple-Cat II modem programs
|
|
I have decided not to include the source files, but many of the operating
|
|
parameters and features of the programs can be changed by changing bytes
|
|
with DDT or EDFILE (Edfile is definitely easier!).
|
|
This is an edited version of the .PRN file which resulted from the
|
|
assembly of the front end module of the program. The addresses are
|
|
the same for both the Softcard and PCPI versions.
|
|
Here is a quick example of how you would use DDT to change an
|
|
operating parameter. Lets say you decided you could really use
|
|
that extra two k of buffer, so you want to tell the program not
|
|
to save the CCP but to warm boot instead (which frees up the memory).
|
|
Looking at the table you would find that the byte SAVCCP is located
|
|
010F in memory. It is set to FF to indicate that saving the ccp is
|
|
desired. To make the change (IMPORTANT: do this on a COPY so that
|
|
you can go back if you mess it up!) you would bring the program in
|
|
with DDT thus:
|
|
DDT CATMSFT.COM
|
|
(some numbers will appear, which you don't need to worry about. If
|
|
you get a ? that means that DDT could not find the file.)
|
|
to change the byte, use the S command (for Set bytes) and type:
|
|
S10F
|
|
DDT responds with
|
|
010F FF (the cursor remains to the right of the byte waiting for
|
|
you to change the value or hit return).
|
|
Type in a zero and hit return. DDT will respond with the
|
|
next byte in memory to be changed. Simply type a period to
|
|
exit the S mode (and a 'return').
|
|
Type control-C to exit ddt. Now you want to save your
|
|
modified file back to disk. The standard command is
|
|
SAVE 85 CATPCPI.COM (for the applicard version)
|
|
SAVE 75 CATMSFT.COM (for the softcard version).
|
|
That's all there is to it. Good Luck!
|
|
(P.S.: If anyone really wants to play with the source code, I can supply it.
|
|
It is not possible to change the slot of the apple-cat from slot two without
|
|
re-assembling. Since 99.9% of the Apple world runs their modems in slot two,
|
|
the best solution is just to move it over. If there is some reason you cannot
|
|
do this, contact me and I will assemble you a version for the slot you need,
|
|
or provide you with the source if thats appropriate. At this point, this
|
|
program must be assembled and Linked with the Assembly Language Development
|
|
System for the Apple II from Microsoft. (I can provide the patches to make
|
|
the assembler work with the Applicard, provided you do own the software.))
