When i send a serial command serialport.write("[exc]") o a specified
serial open serial port. How can i read back the value in a string and
display it in a textbox???
Check the specs on the device you're working with. If it supports the
functionality, it should be easy. Otherwise forget it. Buffering the data
won't do any good either. It's entirely up to the device you're working
with.
Same as putting gas in a car and asking the car how much gas you just put
in... if the car supports that functionality, the info will be right on the
dashboard... otherwise, ain't gonna happen.
