Additions by Don Ward, Foster City, Ca on 11/09/86.
Please note that I am NOT the author of IBMAUX.DOC, IBMAUX1.SYS or IBMAUX2.SYS
and have therefore included an UNMODIFIED copy of the archive IBMAUX20.ARC
which comprises those 3 files.
You may use these programs at your own risk. Neither I nor the authors of the
IBMAUX20.ARC shall be held responsible for any damage or loss of data that may
be incurred through the use of the programs documented herein. You may not
sell the programs. Any conditions stated in IBMAUX20.ARC also apply.
IBMAUX20.ARC provides device drivers AUX1 and AUX2, which give remote console
capabilities to com ports 1 and 2. I wanted two drivers AUX3 and AUX4 which
would provide identical capabilities for my com ports 3 and 4. The programs
IBMAUX3.SYS and IBMAUX4.SYS included here provide those capabilities.
IBMAUX3.SYS (Ports 2E8...2EF, IRQ4) and IBMAUX4.SYS (Ports 2E0...2E7, IRQ3)
were made by using the debugger on copies of IBMAUX1.SYS and IBMAUX2.SYS
respectively.
I added a modification note to the end of the files I created. This increased
the lengths of the files, but not the memory space they take when installed as
drivers.
If you have com ports 3 and above with other addresses, the information below
should help you make suitable modifications. Please note that I did not make
any changes with regard to the interrupt vectors - this seemed to take care of
itself. I ensured this by using a copy of IBMAUX1 to make IBMAUX3, and a copy
of IBMAUX2 to make IBMAUX4, because it happens that my COM3 and COM4 ports use
the same IRQ's as my COM1 and COM2 ports respectively.
Offset is from the START of the file. You need to add 100H if you are using
the debugger in the normal way.
AUX1 thru' AUX4 below refer to IBMAUX1.SYS thru' IBMAUX4.SYS respectively.
All offset and byte values are in hex.
