Options About the baud rate options
The MEI baud rate settings are only valid for EIA-422/485 multi-drop ports.
Supported baud rates for EIA-422/485 with automatic transmitter control
are limited. The “minbaud” and “maxbaud” options allow you to adjust the
range to your requirements. Select the minimum or maximum required
baud rate to adjust the window; defaults for “minbaud” and “maxbaud”
allow you to select any baud rate between 3600 and 230400. Only
“minbaud” or “maxbaud” should be specified, but not both. Whichever
baud-rate option is specified automatically computes the other. The
relationship of “minbaud” to “maxbaud” is: “minbaud” * 64 = “maxbaud.”
minbaud=baudrate
The minimum baud rate. The default is 3600.
maxbaud=baudrate
The maximum baud rate. The default is 230400.
allenables={on|off}
Enables or disables serial-port transmitters.
on
Enables serial-port transmitters.
off
Disables serial-port transmitters.
The default is "on."
