This is a standard internal modem with a 16550 UART.  For Workgroup
for Windows no special installation requirements exist.  Follow the
installation instructions.

Be sure that you have install the latest SERIAL.386 file per
Microsoft's patch.

To maximize modem performance add the following lines to the [386enh]
section of the system .ini file:

	COMxFIFO=2
	COMxTXFIFO=1
	COMxRXTRIGGER=8

CompuServe users should use the latest version of WinCIM (currently
1.4--V1.31 is OK too), select the closest US Robotic script and then
set the init string to:

	AT&F&B1&H1&R2&A3&K3X4^M

with the compression and error correction boxes blank and unchecked.

 Also edit the WinCIM.INI file and add the line:

	HW-FLOW=3

to the [General Preferences] section.

ATTMail users of Versions of Access Plus earlier than V 2.5.1 
need to insure that if they have installed an internal
modem on COM3 or COM4, and that the IRQ is set to 4 for
COM3 or 3 for COM4 because these versions of Access Plus
will not recognize any other settings.  They will also have to
insure that the line in the SYSTEM.INI file that reads COMxIrq=
is set to the proper IRQ (3 or 4) or Access Plus won't work.
Versions 2.5.1 or greater can be configured to non standard IRQs
by creating a BGMAIL.INI file with the lines:

	COMxIrq=y
	COMxBase=z

where y= the IRQ used and z= the base address for the port.  The
defaults are:

com1 - 3F8h, com2 - 2F8h, com3 - 3E8h, com4 - 2E8h

The following modem script should be used.

*USROB288.MOD*
*US Robotics Sportster 28.8 internal modem*
*This script is used to dial out using a US Robotics*
*Sportster modem with Access Plus*
