I have little experience with C#; however, I have managed to connect via RS-232 before. I am having trouble connecting to a USB/virtual serial port device using C#. I can connect via hyperterminal though.
It appears that I can write to the device, I just can't read anything. Right now, I just have a simple program (attached) where I am trying to read in data from the device. I've tried it with and without DtrEnable. I read that with hyperterminal DtrEnable is always true, which is why I put it in my C# program. BTR (see program) is always zero, which is telling me I'm never receiving anything. Once I can start reading data, I will be good. Again, I've done this very same thing with an actual RS-232 serial port and have had no problems. Could my problem be that this is USB/virtural serial port? For those of you familiar with Labview, I am having the VERY SAME problem there too.
Thanks
