Install Null Modem 

It is possible to install a standard 28.8 modem driver in your client. This
does not require actually having a modem, but rather just using a serial port
with this driver attached to it and allowing FREESCO to emulate the modem
responses. The only real difference is in the FREESCO configuration for the
null modem script which is detailed in the FREESCO null modem init script setup.

This null modem driver is for Win 98 clients, but others are availible for other
operating systems.

Open the Windows Control Panel 
Double-click on Modem 
Select Add 
Select Other then Next 
Check the Don't detect my modem and select Next 
Select Have Disk 
Select Browse and point to the location of the Null Modem driver (NullModem98.inf) 
Select OK and follow the instructions on the screen 
Install Dialup Server 

If the system does not have a dialup server (PPP server), you will have to
install one. 
Insert Windows 98 CD 
Select Add/Remove Software 
Double-click on Communications 
Check the box for Dialup Server 
Click OK 
Click OK 
Follow instructions on the screen 
Reboot The Computer
