Serial Port Break (PDA Module and Embedded Module)

»Table of Contents

Sends a break on the output port specified by the port number input parameter for a period of time at least as long as the delay input parameter request.

port number is the serial port. The following table shows the available port number and the corresponding device name on different operating systems.

port number	Windows, Pocket PC	Palm OS	VxWorks	eCos	UNIX
0	COM1	1	/tyCo/0	/dev/ser0	/dev/ttyS0
1	COM2	2	/tyCo/1	/dev/ser1	/dev/ttyS1
2	COM3	3	/tyCo/2	/dev/ser2	/dev/ttyS2
3	COM4	4	/tyCo/3	/dev/ser3	/dev/ttyS3
4	COM5	5	/tyCo/4	/dev/ser4	/dev/ttyS4
5	COM6	6	/tyCo/5	/dev/ser5	/dev/ttyS5
6	COM7	7	/tyCo/6	/dev/ser6	/dev/ttyS6
7	COM8	8	/tyCo/7	/dev/ser7	/dev/ttyS7
8	COM9	9	/tyCo/8	/dev/ser8	/dev/ttyS8

delay is the time interval in milliseconds for the break. The actual period of the break can be longer than this time interval.

error code is the error or warning code. If error code is nonzero, an error occurred. You can wire error code to one of the error handler VIs, which describe the error and give you options on how to proceed when an error occurs.
