If your printer has the optional serial port installed, you can configure the 
port using the DEVPARAM.PS file or using front panel selections.  Refer to 
your Phaser 540 Color Printer User Manual for information on configuring 
serial ports from the front panel.

You should edit the DEVPARAM.PS file before using other files to change 
the printer’s performance.   

The following example sets these parameters:

■

Flow control to Xon/Xoff

■

Parity to none

■

Data bits to 8

■

Stop bits to 2

■

Baud rate to 9600

In this example, the changes are persistent across jobs and across printer 
power cycles; they remain in effect until you change them again.
