[PD] Pd and computer crash/freeze when using [comport], bug?

Pduino has nothing to do with [serial_print]. Such a scenario could 
suggest some problem with Pd when sending data to [comport] and 
processing data received from it (I'm not suggesting it's a problem with 
[comport] since disconnecting it from [serial_print] solved the crash 
problem). I haven't checked your files yet (see my previous reply asking 
for them via a different medium), so I have no idea what could be wrong 
with [serial_print]. I'll get back once I have your files and have 
checked them.
