3 * In an attempt to be nicer to those users who prefer to run newer Linux kernel
4 versions than the Mother's own preference for older host systems, our default
5 Linux version of libserial (the serial port access library underlying all of
6 our tools) now sets the ASYNC_LOW_LATENCY flag in TIOCSSERIAL. Prior to this
7 change, poor performance has been observed on newer Linux host systems where
8 the select system call waiting for serial input would wait some extra 10 ms
9 before returning, majorly slowing down many of our operations. The present
10 change is hoped to alleviate that problem.
