Multiple Tx lines.

Hello, I was wondering is you could use other digital outputs, on the arduino, like a Tx line, so went to print serial data, you can print to different pins? Is this possible? THANKS

Depends on you model, if you want hardware support.

But any model can utilize a software serial library.

Google NewSoftSerial

The arduino Mega will give you 4 'real' ports if you want to go that way or the newsoftserial library is your best bet.
It will let you create TX and RX pins on any digital pin, if you don't need RX then just set it to pin 0 (your normal RX pin)
