About Your Printer Port

Later on, the PORTMAN PC/P software will need to be configured

according to the Port Address (I/O range) and the Interrupt Request

number (IRQ) of the Parallel Port that you have the PORTMAN physi-

cally connected to. Basically put, this information describes where the

computer should look for the PORTMAN PC/P device in order to

communicate with it.

There are a couple of ways to identify your Port’s Address and IRQ. In

Windows 98 or 95, go to the Control Panel from either settings or My

Computer. Open System, click Device Manager, and open the “Ports”

list. Highlight a Printer Port, click Properties, then click Resources.

Here you will view the Interrupt Request, and the Input/Output

range, which is the same as “Address.”

Another way is to run the included program called LPT.EXE. This pro-

gram must be run from DOS. If you are presently in Windows, you

must go to Shut Down, and Restart in MS-Dos Mode, or otherwise quit

(Exit Windows) your Windows session before executing LPT.EXE. The

program is on your PORTMAN software diskette located at the follow-

ing path:

[drive]:\PCPLED\LPT.EXE

Run the LPT.EXE program. It is very simple with onscreen instruc-

tions. The program will tell you how many Parallel Ports it finds, and

what their Port Addresses are. Use this information to help make your

selection in the necessary driver setups. Another way to determine

this information is to consult your computer’s user manual, or consult

the computer’s manufacturer directly.

Ultimately, your Port settings are controlled by the computer’s BIOS,

also known as System Setup or CMOS. In most computers this is

accessed during bootup by pressing a particular key or key combina-

tion, found through an instruction on the screen or in the computer’s

user guide. In some laptops, this is done through a hardware setup

utility found in the “Programs” list from the Start menu (or Program

Manager in 3.1). In a section of the BIOS relating to Peripheral

Configuration, is the ability to assign an IRQ and Address setting to
