RE: make a led blink everytime you get a msg
It's not that hard to do really :/
You need:
* Programming skills
* LED (and maybe resistors)
* Serial cable
Basically it works like this:
You connect the anode leg of the LED up to a data pin on the serial lead/port and connect the cathode (short leg) of the LED to one of the grounds.
Then you just write up some software in whichever programming language you know that accesses this serial port and sends out the corresponding data signal which will turn that data bit on (basically switches +5 through the pin).
