Serial Errors
The printer places an underscore character in the link buffer when it detects an error.
Some printers also display serial errors on the printer operator panel or through
MarkVision as attendance messages, such as a
54 Standard Serial Error or 54 Serial
Option x Error
(x represents the number of the serial port). Serial errors that do not
generate such an error message are:
• Serial Break
• Framing error received simultaneously as a Break
• Powering on a PS/2 connected to the printer
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
