The most frequently encountered problem in installing your modem is related 
to hardward address and IRQ line conflict.  In fact, most people are not 
sure what existing COM Port is already active, and which IRQ lines are free.  
Cheyenne Communications has taken the step to help eliminate the confusion by 
providing a new DOS utility called EZSTART.EXE.  This program must be run in 
DOS without running Windows, and must be run BEFORE you install your new 
modem.  So, if you already installed the modem, please remove it before 
running.

In the DOS prompt, type A:\EZSTART /i [Enter].  It will give you a warning.  
Please type Y to continue.  You'll see (as example):

COM1:   Address 03F8, UART 16450, IRQ 4.
COM2:   Address 02F8, UART 16450, IRQ 3. 
COM3:   Available for internal modem. 
COM4:   Available for internal modem.

For external modem, you may connect the modem cable from your modem to the 
detected COM Port.

For internal modem, you may configure it as:

COM3 at 03E8 using IRQ 5, or IRQ 7
COM4 at 02E8 using IRQ 5, or IRQ 7

The above serves only as our recommendations.  You may connect your external 
modem to one of the above detected COM ports, or if you have an Internal 
modem, set it to the recommended Address (3E8 or 2E8) with IRQ settings of 5 
or 7.  If your system still have problem, you should remove other installed 
cards one by one to see which is conflicting, and make adjustments.

Consult an expert if you are not familiar with the procedures.

Note: We use the standard definition of COM1 (3F8), COM2 (2F8) etc.  which 
may be different than that of Microsoft MSD.EXE.
