Permissions problems efax / dev/ttyS0

[Tomasz Kosinski <mickle@escape.com>]

I recently installed and set up efax. I have added myself to the "fax"
group, yet I am still unable to send/receive faxes as a normal user. As
root, everything works as expected. Sorry for this simple problem, but
don't know how to adjust permissions properly.

Thanks for any advice,

Tomasz
