Problems While Configuring the Serial Network
You can configure the serial network on the terminal by scanning configuration
commands. If you receive an error beep sequence while configuring the terminal, check
these possible problems and solutions. For help, see “Using Serial Communications on
the Terminal” in Chapter 4.
Problem Solution
The terminal is configured for
Configurable protocol. You are
scanning or entering a configuration
command to set a serial port
parameter and hear three low beeps.
For example, you are trying to
configure EOM, SOM, or
Handshake. The order in which you set serial port commands is important. Configurable
Protocol uses EOM to determine the serial communications mode. When
EOM is disabled, the terminal communicates in Character mode. When EOM
is enabled, the terminal communicates in Frame mode. Follow these rules to
configure the serial port for Configurable protocol.
To use Frame mode, you need to set EOM first. Next configure Configuration
Commands Via Serial Port, Handshake, LRC, SO, and then Poll. To use
Character mode, you need to disable these same parameters in reverse order.
You are configuring SOM and hear
three low beeps. You have configured SOM to an invalid value. SOM cannot equal the same
value as EOM. You cannot set SOM to any of these values: AFF (ACK), DLE,
NEG (NAK), Poll, RES (EOT), REQ (ENQ), SEL, XOFF, or XON. You need
to change the value of EOM or SOM.
For help, see “Start of Message (SOM)” in Chapter 8.
