SetUp Command 5-6
Command:
$1RR
Response:
*
Up to this point all communications have been sent at 300 baud. The module
will not respond to any further communications at 300 baud because it is now
running at 9600 baud. At this point the host computer or terminal must be set
to 9600 baud to continue operation.
If the module does not respond to the new baud rate, most likely the setup
data is incorrect. Try various baud rates from the host until the module
responds. The last resort is to set the module to Default Mode where the
baud rate is always 300.
Setting a string of RS-232C modules to a new baud rate requires special
consideration. Refer to Chapter 3 for instructions.
