Root can't use serial devices
I am having weird problems with serial devices on my system. The main
symptom is that root is unable to use the serial devices. User blp
(me) can use the serial devices--kermit, minicom, mserver all work
when run as blp--but root cannot. The one exception to this is pppd,
which only works when run as root, but this might be related to the
permissions on /etc/ppp and /etc/chatscripts.
/dev/ttyS0 is set up as follows:
crw-rw---- 1 root dialout 4, 64 Jan 7 12:49 /dev/ttyS0
User blp is a member of group `dialout'. Root is not, but why should
this matter?
Anybody have advice? This is very frustrating because it means I have
to run mserver as user blp, which doesn't make sense at all.
