Control Characters for the LA75 Plus
Companion Printer
This chapter describes the control characters for the LA75 Plus Companion
Printer and their functions. The control characters are:
• Bell, described in Section 7.1
• EOT, described in Section 7.2
7.1 Bell
The LA75 Plus Companion Printer has an audio indicator, or bell. The bell
can be configured using setup to sound one beep, sound three beeps, sound
continuously, or not to sound at all when an error occurs. When the device
receives a BEL (Bell) control character, it always sounds one beep.
7.2 EOT
When Disconnect on EOT is enabled by the setup facility, the DTR signal on
the serial port is dropped for 5 seconds when the EOT control code is received.
This feature applies only if the serial port is active. See the setup feature
Disconnect on EOT (DEC 8), in the LA75 Plus Companion Printer Installation
and User Guide.
