SELECTING A COMMUNICATIONS PORT

Most computers allow two communications ports, Com 1 and Com 2, to identify 
the address or location in computer memory of each serial device that is 
connected to the computer.

The factory setting is Com 1.  If you use a mouse or other serial device, 
check its board setting to see which Com port it addresses.  If the other 
device is set for Com 1, you must change the Com port setting on your modem to 
Com 2.  If you set two devices to the same address, your modem or the other 
serial device does not function properly.

If necessary, before installing the modem, change the Com port setting as 
shown below.

If your communications software allows you to select a Com port, be sure to 
select the same com port that you selected with the jumpers on the modem.
