Hi, I'm trying to create a form to send and receive data on a serial port.
The idea is:
When the form loads it opens the COM port
A separate Sub handles any new data on the port and saves it in a text box
When a button or enter key is pressed the string in a text box is sent to the serial port...
I found the problem. I was using a virtual serial port bridged to another virtual serial port (via software) so I could interact with the program using HyperTerminal.
Once I swapped over to a real serial port the issue went away.
Hi I'm trying to write data to a serial port however I seem to be constantly getting the "catch" situation occurring when I call this code:
'Send Data on Serial Port
Sub SendSerialData(ByVal Description As String, ByVal output_data As String) 'Send strings to ComPort
