Putting in a PAUSE that is as long as the time it takes to send the string does cure the problem, but my goal is to really understand what PBP is doing.
I have what may be the "worlds largest PBP Program" (My 8722 is nearly full), and now I'm adding SNMP protocol and another layer of interrupts (assembler). I'm noticing some weird behavior, and I'm trying to understand what is going on.
