Communication Parameter

The command to set RS-232 communication parameters is uart.

"set uart (parameter)"

Specify a string of the following form in parameter.

"(baudrate)[parity[data bit[stop bit[flow control]]]]"

※ (): mandatory, []: optional

Paramater Values Description Default Value
baudrate 1200 ~ 115200 baudrate(bps) 115200
parity N, E, O, M or S parity bit
(N: None, E: Even, O: Odd,
M: Mark, S: Space)		 N
data bit 8 or 7 data bit 8
stop bit 1 or 2 stop bit 1
flow control N, H or S flow control
(N: None, H: RTS/CTS, S: Xon/Xoff)		 N

$sid = 14;
spc_reset();
spc_sync_baud(115200);

spc_request_dev($sid, "set uart 115200");
echo spc_request_dev($sid, "get uart"), "\r\n";   // output: 115200N81N

spc_request_dev($sid, "set uart 115200N81");
echo spc_request_dev($sid, "get uart"), "\r\n";   // output: 115200N81N

spc_request_dev($sid, "set uart 9600E72H");
echo spc_request_dev($sid, "get uart");           // output: 9600E72H

?>

※ Note: The flow control(H and S) and the setting of inter frame gap ("set ifg") cannot be used at the same time.
