Serial Computer Configuration Recommendations (RS-232C)

For correct operation of the serial interface, your printer and your computer operating system must be configured identically. The following is an example of how to configure DOS for the printer using serial DTR protocol:

DOS:

From the DOS prompt, enter the following commands:

mode comy:9600,n,8,1,p mode lptx :=comy

where x equals 1, 2, or 3, and y equals 1 or 2

Include these two command statements in the AUTOEXEC.BAT file on the computer so they run each time your system starts operating.

Once this is set, to copy to the communications port again use the copy command:

copy 'filename' lptx
