PURPOSE
-------

This facility has been designed to provide the Sysop with a way to
allow visting Sysops to exit to DOS for the purpose of assisting the
HOST Sysop with an installation problem. The keyboard and screen
redirection perform by this facility is not as robust as that provided
by using either CTTY COM1 or CTTY COM2, but this facility has the
advatange of permitting both Sysops to be able to see what is going
on. This capablity enhances the Sysops ability to guide each
other through DOS and to work together on solving a problem.




INTRODUCTION
------------

IBMAUX1.SYS and IBMAUX2.SYS are a revised version of the IBMAUX.SYS
device driver which is an original work of Wayne E. Conrad. I have
simply modified the code to permit the user to establish a
simultaneous keyboard and screen seesion at the DOS prompt with either
COM1 or COM2 by using the commmand CTTY AUX1 or CTTY AUX2. The
original version driver named IBMAUX.SYS only supported COM1 with the
command CTTY AUX.





HOW TO USE THE IBMAUX DEVICE DRIVERS
------------------------------------

To use this facility, you would code the following statement in your
CONFIG.SYS file:


device=[d:][path\]IBMAUX1.SYS


if you intent to establish a simultaneous session through COM1, or


device=[d:][path\]IBMAUX1.SYS


if you intend to establish a simultaneous session through COM2.


The drive quailifer [d:] and the path qualifer [path\] are optional
and may be omitt6 #tV'^

of the current command line and to retype the command.

3) This facility will hang your system if the device driver is invoke
via the CTTY command but there is no body for the device driver to
talk to via the modem.
