port's communication
parameters.
TSET BAUD
Temporarily set the
RS-232/422/485 port's
communication
parameters for a device.

Description
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop>
[485 <Enable | Disable>]'"
Variables:
Baud: baud rates are: 230400, 115200, 76800, 57600, 38400, 19200, 9600,
4800, 2400, 1200, 600, 300, 150.
Parity: N (none), O (odd), E (even), M (mark), S (space)
Data: 7 or 8 data bits
Stop: 1 or 2 stop bits
485 Disable: Disables RS-485 mode and enables RS-232/422
485 Enable: Enables RS-485 mode and disables RS-234/422
Note: The only valid 9 bit combination is (baud),N,9,1.
Example:
SEND_COMMAND SOMEDEVICE_1,"'SET BAUD 115200,N,8,1, 485
ENABLE'"
Sets the SOMEDEVICE port's communication parameters to 115,200 baud, no
parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
TSET BAUD works the same as SET BAUD, except that the changes are not
permanent, and the previous values will be restored if the power is cycled on the
device.
Syntax:
SEND_COMMAND <DEV>,"'TSET BAUD
<baud>,<parity>,<data>,<stop> [485 <Enable | Disable>]'"
Variables:
Baud: baud rates are: 230400, 115200, 76800, 57600, 38400, 19200, 9600,
4800, 2400, 1200, 600, 300, 150.
Parity: N (none), O (odd), E (even), M (mark), S (space)
Data: 7 or 8 data bits
Stop: 1 or 2 stop bits
485 Disable: Disables RS-485 mode and enables RS-232/422
485 Enable: Enables RS-485 mode and disables RS-234/422
Note: The only valid 9 bit combination is (baud),N,9,1.
Example:
SEND_COMMAND RS232_1,"'TSET BAUD 115200,N,8,1 485 ENABLE'"
Sets the RS232_1 port's communication parameters to 115,200 baud, no parity, 8
data bits, 1 stop bit, and enables RS-485 mode.
Syntax:
SEND_COMMAND <DEV>,"'TXCLR'"
Example:
SEND_COMMAND RS232_1,"'TXCLR'"
Clears and stops all characters waiting in the RS232_1 device's transmit buffer.
Syntax:
SEND_COMMAND <DEV>,"'XOFF'"
Example:
SEND_COMMAND RS232_1,"'XOFF'"
Disables software handshaking on the RS232_1 device.
