- PATCH TO ALLOW COMMANDER MAIL
- TO USE COM3 OR COM4
-
- NORTON COMMANDER VERSION 3.0
-
- In order to get the Commander Mail module of the Norton
- Commander to address either COM3 or COM4 in place of COM1
- or COM2, you will need to patch the MCIDRIVR.EXE program.
-
- The program messages will still refer to COM1 and COM2, but
- COM3/4 will actually be used.
-
- In the MCIDRIVR.EXE program two bytes need to be changed:
-
- At offset 10FD8H change the byte from F8H to E8H.
- At offset 10FDAH change the byte from F8H to E8H.
-
- Reverse the changes to go back to COM1/COM2.
-
- Using DISKEDIT.EXE in Norton Utilities 5.0 (or NU.EXE in Norton
- Utilities 4.0 or 4.5) is the easiest way to make the change, or
- you can use DOS's DEBUG if you know how to use it to patch .EXE
- files (this is left as an exercise for the reader).
