Re: [Jython-users] Read/write serial data

[Jon C. <jon...@gm...>]

Not jython-specific, but have you tried pyserial by any chance?

It looks pretty simple:

https://pyserial.readthedocs.io/en/latest/shortintro.html

>>> ser = serial.Serial('COM3', 38400, timeout=0,...                     parity=serial.PARITY_EVEN, rtscts=1)>>> s = ser.read(100)       # read up to one hundred bytes...                         # or as much is in the buffer
