# [PATCH] pl2303.c: do not reset termios settings in each open()
# 
# this is a patch which avoids resetting the termios settings to default
# values (9600 Baud etc.) in each call to pl2303_open (). It does this
# only on the first call to pl2303_set_termios. After that it sets the
# termios to the last stored values.
# 
# This way commands like
# stty -F /dev/ttyUSB0 115200
# work the same way as with other serial ttys.
