Bugfix: 1.5 stop bits for serial port should set the posix stop bit flag (#5873)
1.5 stop bits have not been handled at all.
According to this documentation of the 8250 UART:
http://stanislavs.org/helppc/8250.html
a set bit 2 in the LCR register means stop bits = 1.5 for 5 bit words or 2 for 6, 7 or 8 bit words.
That is the reason why pyserial also sets the bit:
