Sending a "BREAK" with VISA Write

[Garcas]

I am developing a driver in LabVIEW for a Serial Instrument and I have found the following problem.

In the instrument documenteation it says that to reset the serial interface and delete the error buffer, you can send a BREAK. A BREAK is generated by keeping the data line high for at least as long time as it takes to send a character.

I have tried sending a 0xFF character with a VISA Write but it doesn't work. Any ideas ?

Thanks a lot

LabVIEW has given you a way to do this, it's just a little hard to find sometimes. The function you are looking for is in: Functions->VISA-> VISA Advanced->Interface Specific->Serial->VISA Serial Break.vi. This is in LabVIEW 6.02 anyway. If you're using a different version, there should be something similar. Hope this helps.
