Serial Port Silliness
Hello,
I'm just trying to get into some serial port programming. At the moment I'm treating it exactly as I would a file, so I get a handle using CreateFile and "\\\\.\\COM1" for the filename. Then I engage in a spot of send and receive with my device, using ReadFile and WriteFile.
The problem is, although I'm able to transmit properly, any bytes I receive seem to have their most significant bit cleared. 7 bit transfer? How do I turn this off?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Now see here's the funny thing:- you go through all the rigmarole of checking these settings in the Device Manager to make sure they're correct, and yet when you finally get a handle to the port Windows decides you'd be better off with 1200 baud, 7N1. GAAAAAHHHH!
Thanks Salem.
