>Does anyone have any information on the proper way to program RS232 stuff? I'm writing an interface using MSCOMM32.OCX and need to know if I'm doing it right. The main question I have is what is the best way to monitor the comm port? Right now, I just wait for the OnComm event to fire and the process what's in the buffer, but sometimes, I don't get all the data at once, sometimes it's split up, and I'm wondering how to make sure I get it all when I do lcInputBuffer = CommCtrl.Input.

Hi Jim,
One of the traps of MSComm is that OnComm event does not always fire when VFP is looping through method code. You some times have to place DOEVENTS in looped code, to give MSComm events. This is tricky, because DOEVENTS includes all windows events, and it may slow your code drastically. Remember also, that you are responsible for checking overflow events in your code. This is probably the most overlooked coding, that causes missing data.

Good Luck,
