That's exactly the point. But the latter solution wouldn't really hurt
me, because input in MintNet is already processed asynchronously via
addroottimeout(). So I could simply use kerinfo->post_sig() in the
right place to do the job while I had to setup a different thread with
Pexec() and would have perhaps all the problems Stephen has with its
update daemon and Multitos without post_sig().

BTW: Have you thought about a concept for adding line discipline stuff
to your driver? I would really like to avoid implementing serial drivers
into MintNet...


All the best, Kay.
