How do I load serial buffer during transmission

[Piraz]

I'm writing with my serial port 19200 bauds and the transmission is OK. When the buffer is empty the serial reload it and stops the transmission (BAD THING). I'd like to reload the buffer during the transmission. I need only to write on serial, no read. I'm using LabView 5.1.1. Thanks for helps.

Hello-

Be sure to use the VISA serial VI's for LabVIEW. It's surpizing that the transmission stops. Try using highlight execution to verify the VI behaves as expected. Also, it may help to right-click on the VI and Do I/O synchronously.
