When using Crosstalk for Windows with communications ports 3 and 4,
you'll need to use the SETC1234.EXE utility to set up your system
before you run Windows.  This procedure is described in this text. 

You'll also need to configure your Windows SYSTEM.INI file according
to the addresses and IRQ (Interrupt Request) numbers used by the
ports.  This procedure is described in the Windows SYSINI2.TXT file.

Microsoft Windows requires serial port addresses to appear in your
system's BIOS data area.  If you know how to use DOS's DEBUG utility,
you could enter the addresses yourself into the appropriate
locations.  Using the SETC1234.EXE utility program allows you to enter
these addresses without using DEBUG, and makes the procedure easy.
SETC1234 is used at DOS, and can be part of a batch file.  We
recommend adding SETC1234, with the appropriate arguments, as
described below, to your system's AUTOEXEC.BAT file.

As previously mentioned, SETC1234 is invoked at the DOS prompt.  If
SETC1234 is entered without an argument, the addresses for COM1, COM2,
COM3, and COM4 are set to their defaults of 03F8, 02F8, 03E8, and 02E8,
respectively.  These are the default addresses used by SETC1234, and
are the most widely used values.

You may provide arguments to SETC1234 which specify the addresses (in
hex) to use.  For example:

SETCOM34 WWWW XXXX YYYY ZZZZ

Where: 
	WWWW is the address to use for COM1
	XXXX is the address to use for COM2
	YYYY is the address to use for COM3
	ZZZZ is the address to use for COM4

So, for example, if your COM1 and COM2 are at standard addresses and your
COM3 is at address 0180 and COM4 at 0190, you would enter the following
command at the DOS prompt:

SETC1234 03F8 02F8 0180 0190

If you would like information about SETC1234, or would like to see the
current address settings, enter a question mark as the argument.  For
example:

SETC1234 ?

You will need to set these port addresses using SETC1234 each time
your system is rebooted.  It is for this reason that we recommend
adding SETC1234 to the system's AUTOEXEC.BAT file.  SETC1234 does not
interfere with any aspect of the system's operation.
