Need help with timeout

[Christopher4187]

I have RTFM about serin2 and I think I need a timeout function. The program works fine but if I the communication is lost for a second, the program locks up. I think I need a timeout but it is not fully explained in the manual. When the program "locks" up (I think it's just getting stuck at the serin2 part), I have to cycle the power on the PIC or reload the program and then it's OK. I have searched this forum for related topics and I found some but I am lost. If I was communicating PIC to PIC I would be fine but I am communicating with the Parallax PINK.

Nevermind. I found a post from BobK on the 30th of January and his line of code worked perfect!

Thanks!
