To specify serial port settings

Many applications provide a way for you to adjust the settings for serial ports they
use. Other applications don't let you change serial port settings. However, you can
use Control Panel to set the basic serial port settings—the ones used by an
application that doesn't change settings.
In Windows 95
1. Open the System Properties window.
2. Click the Device Manager tab to see a list of serial (COM) ports.
3. To view the settings for a COM port, select the port and click Properties. (The
serial port is normally COM1, and the physical infrared port is normally COM2.)
In Windows for Workgroups
• Open Control Panel and double-click the Ports icon. Click the port you want to
set up, then set its parameters. For details, see the Windows Quick Start manual.
Hardware Settings
The changes you make to the advanced settings for a serial port should match your
hardware settings. The built-in advanced settings are listed below—you shouldn't
use different settings in any applications.
• COM1: address 3F8 hex, interrupt 4.
• COM2: address 2F8 hex, interrupt 3.
• COM3: address 3E8 hex, interrupt 4.
• COM4: address 2E8 hex, interrupt 3.
