Mike, thanks for your response. I looked at -substringWithRange but could not discern how exactly I would apply it. I will take another look.

Thanks, Jim

The receive buffer in the chip I am talking to will only take 80 characters before an XOFF (buffer 2/3 full).  XON occurs when the chip buffer is reduced to about 1/3 full.  This routine is in a thread that reads data from the chip as well.
