Serial Errors

Interfaces

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 Professional as attendance messages, such as a

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 an IBM-compatible personal computer 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
