Description:
The system output port settings including RS-232 BAUD rate, parity, and number
of bits per character may be established to specified values.
Purpose:
Sets the output BAUD rate for RS-232 port to a specified rate. The parameters
are:
rate
is specified as follows:

2,400

19,200

bits
7 or 8
Note 1.
The number of stop bits is always one (1).
Note 2.
For seven (7) bits, parity may be NONE, ODD, or EVEN. For eight (8)
bits there is never a parity bit; i.e., NONE.
Note 3.
8 data bits are required when using either the standard binary format or
the 16 BIT format.
Relatives:
None.
Default:
Based on I/O switch settings.
Example:
Suppose there is a requirement to change the baud rate (in software) to 19,200
baud, while the rate set by the I/O select switches is 115.2K baud. It can be
accomplished with the following command, without turning off and restarting the
system.
o192,N,8,0<>
The system serial communication parameters will now be 19200-baud, no parity,
8 data bits, and 1 stop bit.
NOTE:
The communication software will now have to
be re-set to the new baud rate (19,200) in order for communication with the
system to continue.
