> Let me add another vote/request for pySerial support.  I've been using it with python 2.7 on OS-X, unaware that there wasn't a path forward to python 3.x.  If an external sensor absolutely positively has to be readable, then RS-232 is the only way to go.  USB interfaces can and do lock up if recovery from a power failure puts power on the external side before the computer has finished initializing the CPU side.  RS-232, bless its primitive heart, could care less.

Then 'someone' should ask the author his intentions and offer to help or 
take over.

I did some RS-232 interfacing in the  1980s, and once past the fiddly 
start/stop/parity bit, baud rate, and wiring issues, I had a program run 
connected to multiple machines for years with no more interface problems.
