User's Manual

Using the Control Panel 3-17
Serial Menu
The Serial menu is available only when you have installed the
optional LocalTalk/Serial module or the Serial interface card
(described in Chapter 4) and have set the Emulation menu to
Serial
(see page 3-10). You may need to change these settings to
match the serial settings used by your computer. For
information about your computer’s serial settings, see your
computer manual.
You can change serial printer settings through either the Serial
menu or the Remote Control Panel utility (see the Technical
Information manual). Settings made using the Remote Control
Panel utility override those made using the Serial menu.
* See your computer manual and software documentation for the correct
setting.
