characters to the | |||
Master (default). |
| SEND_COMMAND <DEV>,"'RXON'" | |
| Example: | ||
|
| SEND_COMMAND RS232_1,'RXON'" | |
| Stops the RS232_1 device from transmitting received | ||
| characters to the Master. | ||
|
| ||
SET BAUD | Syntax: | ||
Set the |
| SEND_COMMAND <DEV>,"'SET BAUD | |
port's communication |
| <baud>,<parity>,<data>,<stop> [485 | |
parameters. |
| <Enable Disable>]'" | |
| • Baud: 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 Bits: 7 or 8 data bits | |
| • | Stop Bits: 1 and 2 stop bits | |
|
| The only valid 9 bit combination is (baud),N,9,1. | |
| • 485 Enable: Enables | ||
|
| ||
| • 485 Disable: Disables | ||
|
| ||
| Examples: | ||
|
| SEND_COMMAND RS232_1,"'SET 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 | ||
| |||
|
| ||
TSET BAUD | Syntax: | ||
Temporarily set the |
| SEND_COMMAND <DEV>,"'TSET BAUD | |
| <baud>,<parity>,<data>,<stop> [485 | ||
communication parame- |
| <Enable Disable>]'" | |
ters for a device. | • Baud: 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 Bits: 7 or 8 data bits | |
| • | Stop Bits: 1 and 2 stop bits | |
|
| The only valid 9 bit combination is (baud),N,9,1. | |
| • 485 Enable: Enables | ||
|
| ||
| • 485 Disable: Disables | ||
|
| ||
| Examples: | ||
|
| SEND_COMMAND RS232_1,"'SET BAUD | |
|
| 9600,N,8,1 485 DISABLE'" | |
|
| SEND_COMMAND RS232_4,"'SET BAUD | |
|
| 115200,N,8,1 485 ENABLE'" | |
| 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. | ||
|
| ||
TXCLR | Syntax: | ||
Stop and clear all |
| SEND_COMMAND <DEV>,"'TXCLR'" | |
characters waiting in the | Example: | ||
transmit out buffer and |
| SEND_COMMAND RS232_1,"'TXCLR'" | |
stops transmission. | Clears and stops all characters waiting in the RS232_1 | ||
| device's transmit buffer. | ||
|
| ||
XOFF | Syntax: | ||
Disable software |
| SEND_COMMAND <DEV>,"'XOFF'" | |
handshaking (default). | Example: | ||
|
| SEND_COMMAND RS232_1,"'XOFF'" | |
| Disables software handshaking on the RS232_1 device. | ||
|
| ||
XON | Syntax: | ||
Enable software |
| SEND_COMMAND <DEV>,"'XON'" | |
handshaking. | Example: | ||
|
| SEND_COMMAND RS232_1,"'XON'" | |
| Enables software handshaking on the RS232_1 device. | ||

NXC-COM2 Send_String Escape Sequences
This card has some special SEND_STRING escape sequences:
If any of the 3 character combinations below are found anywhere within a
SEND_STRING
program instruction, they will be treated as a command and not the literal characters:
27,17,<time> | Syntax: |
Send a break character | SEND_STRING <DEV>,"27,17,<time>" |
for a specified duration to | time: 1 - 255. Measured in 100 microsecond increments. |
a | Example: |
specific device. | SEND_STRING RS232_1,"27,17,10" |
| Sends a break character of 1 millisecond to the RS232_1 |
| device. |
|
|
27,18,0 | Syntax: |
