Xadow Breakout out/in as Softserial port???

Could be possible define a softserial port using PB1/PB2 signals of the Xadow Breakout board??

I want use a new port to comunicate with another module that use a comm port and i cant not use the serial port of xadow board because is busy communicating with another module.

Im using Xadow GPS board throug the serial port and I want to use a GSM/GPRS module to send the info to any mobile and use a softserial port to communicate with it.

Is possible get an example code???

Thanks in advance!!!

The TX and RX of Xadow GPS have been connected to PD2 and PD3, so you can’t use any software serial port for Xadow GPS.
