Hi,
I am using SL 5.4 (2.6.18-164.6.1.el5, x86_64, no i386 at all) and have a
problem with using minicom as a standard user. I would appreciate any help!
I have a user named "usv" which is in two groups - usv and uucp. I installed
minicom and when I first tried running it, minicom asked me to create a
default file in /etc by running "minicom -s" as root. I did that and could
run minicom without any problems as root. However, when I run "minicom -s"
as user usv, and try to change serial port settings, I am not allowed to
change the serial port setting. I get a message "You are not allowed to
change this parameter". I am allowed to change only options E, F and G
(baud, parity, number of bits and flow control). I tried searching on
internet about this, but could not get any answer. I was wondering if I am
missing any group/permissions etc and would really appreciate any help!
My minicom binary has ownership/permissions:
-rwxr-xr-x 1 root uucp 174136 Apr 7 2007 /usr/bin/minicom
The serial lines are mostly root only, but one is accessible by uucp:
# ls -l /dev/ttyS*
crw-rw---- 1 root uucp 4, 64 Aug 25 06:50 /dev/ttyS0
crw------- 1 root root 4, 65 Aug 25 06:50 /dev/ttyS1
crw------- 1 root root 4, 66 Aug 25 06:50 /dev/ttyS2
crw------- 1 root root 4, 67 Aug 25 06:50 /dev/ttyS3
/etc/minicom.users also controls access to minicom configs.

It looks as though you are supposed to use a different setting
file for each port. If you want a setting for ttyS0, first run
"minicom -s ttyS0" as root and then "minicom ttyS0" as usv
Which settings are you trying to change just for user usv ?
With a system config for each serial line (or connected device)
I would not expect users to need different settings for A-D.
