“ATS100” Set Port Baud Rate
S-register 100 sets the baud rate of the connected serial port. The values for S-register 100 are limited to
{110, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200}. To set the baud rate for a specific
port, the command is appended with “
:0
” for the main port and “
:1
” for the auxiliary port.
ATS100=300<CR>
: Sets the baud rate to 300 on the current port.
ATS100=115200:0<CR>
: Sets the baud rate to 115200 on the main port.
The value store in s-register 100 will not be applied immediately. It will only become active once the
AT&W1
command is executed.
C.2.28
“ATS101” Set Port Parity
S-register 101 sets the parity of connected serial port. The parity can be set for a specific port by appending
to the command “
:0
” for the main port and “
:1
” for the auxiliary port. There are three options for the parity:
ATS101=0<CR>
: Disable parity on current port.
ATS101=1:0<CR>
: Odd parity on the main port.
ATS101=2:1<CR>
: Even parity on the auxiliary port.
