terminals do not use an RS-232 interface so do not need this setting. However, it
is supported for compatibility with other IPPs.
This packet command selects the baud rate for the RS-232 communication
interface. Through packet command 01 diagnostic 00, the current baud rate can
be determined. The factory default is 1200 bps.
The baud rate setting is stored in backup RAM. After a power cycling memory test
or loss of backup battery power, the baud rate setting is reset to the default.
