Hello,

I have been able to compile most of the sample linux prg's OK and have written a few of my own that compile and run OK.
I have a need to do some serial communications (RS232). These are the linking errors I get when trying to compile.

Is there a library that needs to be linked?

Do I need the Commercial (Paid) Version?

OR am I using the wrong functions for reading and writing to the comm ports??

Thanks,

Brad
