Baud Rate Bn
The Baud Rate command programs the speed at which serial data is
transmitted and received by the selected serial port. The Port Select command (Pn)
is used to select the serial port regardless of addressing mode in use. Additionally the
CTS
line may be used to input a clock signal which is sixteen times the desired baud
rate if B11 is selected. The factory default setting as set by the Save Configuration
command (S0) is B9, 9600 baud.
NOTE: The sum of the baud rates for all four ports cannot exceed 38,400 baud or data
may be lost.
