CAnnot access /dev/ttys1 with Minicom on Korn Shell

Yves Plasse · 01-09-2009, 07:50 PM

I am using Slackeare 12.2.

When I use Minicom as Root, I am able to dial out on /dev/ttys1. When I log as a normal user with its default Korn Shell (ksh), I get the message 'minicom: cannot open /dev/ttys1 - Permission denied' after starting it.

I tried to comment out /dev/ttys1 on the file /etc/serial.conf without success. Obviously, there must be a way to allow the access to /dev/ttys1 to a user. Can somebody tell me how?

Thank you,
Yves Plasse.

make sure in your user manager the user has daemon and bin permission and plugdev.

This user is part of the daemon, bin and plugdev groups. There must be something else...

Thank you,

perhaps you do not have write permission on the folder wherein the config file for minicom is being created?

I finally found the problem. After looking at all replies and reading a bit. I found somewhere that the message 'Permission Denied' is most likely related to a file permission problem. I logged as root and checked the permissions for /dev/ttyS1 to find that it was allowed read/write permission to root and uucp and none to the others. I just had to make my user part of the uucp group to be able to use minicom and access my modem on COM2.

Thank you all.
