Control Characters for the LA310
MultiPrinter
This chapter describes the control characters for the LA310 MultiPrinter and
their functions. The control characters are:
• Bell, described in Section 14.1
• EOT, described in Section 14.2
• ENQ, described in Section 14.3
14.1 Bell
The LA310 MultiPrinter has an audio indicator, or bell. The bell can be
configured using setup to sound one beep, to sound three beeps, to sound
continuously, or not to sound at all when an error occurs. When the device
receives a Bell (BEL) control character, it always sounds one beep.
14.2 EOT
When ‘‘DISCON/EOT’’ is enabled by the setup facility, the DTR signal on the
serial port is dropped for 5 seconds when the End of Transmission (EOT)
control code is received. This feature applies only if the serial port is active.
See the setup feature DISCON/EOT, in the LA310 MultiPrinter Installation
/User’s Guide.
14.3 ENQ
When ‘‘ANSWERBACK/ENQ’’ is enabled by the setup facility, the answerback
message is sent by the printer on receipt of the Enquire (ENQ) character.
This feature only applies when the serial port is active. See the setup feature
ANSWERBACK/ENQ in the LA310 MultiPrinter Installation/User’s Guide.
Also see the Load Answerback (DECLANS) command in Appendix C.
