The parameter baud specifies the baud rate that will be used. The permitted values of parameter baud
are shown in the table below.
If the optional port name parameter is missing, then the current control port will be assumed.
If the baud rate of modem Port D/E is changed while the modem is in use, the new
baud rate will not take effect until the caller disconnects from the modem.
If no parameters are specified, the HD9084 will respond with a report of the communication parameters
of all the COMM ports as shown below.
Port A: 1200 7 Odd
Port B: 9600 8 None
Port C: 1200 7 Odd
Port D: 4800 8 None
Examples: ^AI<sp>19200<cr> Set baud rate to 19200.
^AI<sp>P1<sp>96<sp>8<sp>N Sets Port A to 9600,8,N.
