I have one tiny irritating problem :
Here is what I do:
Clear Request To Send (~CRTS)
Read from port
Should the device be turned off whilst readings are being taken,
I get the previous reading, which means I need to clear the
input from the device, before reading from the port. What
usually happens is that I get an additional reading without
any input, then reading returns to normal.
How do clear information that has been previously sent to the port?
