Its unlikely to be the Python - so far when I have had Serial Hassles - its been either finger trouble on my part, or some underlying thing freaking out - four ports at 115200 means a char potentially every 21 microsecs - not quite trivial. - Hendrik -- http://mail.python.org/mailman/listinfo/python-list
