When my Windows 7 install boots up, I can't access my Serial Ports from the command prompt.
If I send "ECHO NET 4 >Com4"
I get nothing.
If I open a terminal program, such as Hyperterm Private, and access the port, then close the terminal program and send:
"ECHO NET 4 >Com4"
Then it behaves as I would like it to.
It's like a terminal program 'wakes up' the com port or serial port.
Any way I can waken the port without opening a terminal program to do it?
