- 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.
