Verifying Serial Parameter Settings
Next, you must make sure the serial parameter settings are the same
between the computer and the printer. Consult your computer and
software documentation to determine the settings your computer
uses. Then compare these to the printer's settings in the following
table.
Item
Baud rate
Data bits
Stop bits
Parity
Pacing (protocol)
DTR polarity
ROBUST (XON/XOFF)
If the settings match, the installation is complete. If the interface
parameters of the printer and the computer do not match, the
message display indicates COMM.ERROR. The printer may not
respond at all or it may print wrong characters. Change the settings
in one of the two ways:
• Change options of the serial menu in setup mode.
• Set permanent defaults in your computer to match the printer's
defaults.
On an IBM PC or compatible computer running MS-DOS, you can
set permanent defaults by placing the following commands in your
AUTOEXEC.BAT file:
MODE COM1:9600,N,8,1,P
MODE LPT1:=COM1:
Also make sure that the file MODE.COM is in your boot directory.
Then whenever you boot your computer, the computer will print
through the serial port using the printer's settings.
