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

[Martin Peach]

I was able to get the files by right-clicking on their icon and doing 'save as'.
In my experience the only way [comport] crashes Pd is when you try to
print its output to the console while it's receiving huge amounts of
data. This causes the messaging pipeline to the TCL process to fill up
until it has no more space, as it is unable to keep up with the
incoming stream..

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.
