Im beginning to suspect that either your serial port is not configured properly, or that the device is not responding. I highly recommend you attempt to communicate with the device using some other means I use hyperterminal frequently. You can then play around with all of these settings bitrate, parity, data bits, stop bits, flow control until you find the set that works. The documentation for the device should also specify these settings. Once I figured those out, I would make sure my. NET Serial. Port is configured properly to use those settings. Some tips on configuring the serial port Note that when I said you should use the following constructor, I meant that use that function, not necessarily those parameters You should fill in the parameters for your device, the settings below are common, but may be different for your device.
