Hey everyone, I am trying to write a serial application that will be used as a subvi. For the most part, it tends to work on and off, which is not good. I send commands to the device and it works. Other times it does not. I am not sure if this should go in this forum. This serial application is being built using the PDA toolkit, so i assume so. I have some screenshots, describing my problem. ANyone familar with serial communication, please chime in, your help is appreciated.

From my experience, you generally end up re-writing most of the code. Their isn't a hack. Also, usually an application that is compiled for the PDA straight from the windows version tends to run slower on the PDA. The PDA version still has some issues with it being buggy and you'll encounter lots of them with arcane error codes when you try to build a WINCE. Also the toolkit is different, some things are not supported.

You can purchase a CF card to serial. WHich is what I am using on an HP PDA. You can find it here: http://www.siig.com/product.asp?catid=10&pid=580 It works well. As for serial implementations, you can try using their standard VI's although they are a good starter they don't serve well as they are for subvis.
