error controlling tty (ioctl)

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Dear mgetty users,

I'm new to the list and I have problems to make mgetty work for FAX-use.

When I start mgetty by calling <path>/mgetty ttyS1 everything works
fine.
But as soon as a FAX call comes in, mgetty is not able to receive the
FAX.

Here's a cut from the log:

I found out that the errormessage 'cannot set controlling tty (ioctl)'
comes from
the file mg_m_init.c, line 404. But why does this happen?

I checked the following things:

*there is no other program running using ttyS1 or modem or cua... there
is only mgetty.
*/dev/ttyS1 is owned by user uucp and belongs to group uucp. This is
mentioned in
 policy.h, too.
*there is no lockfile in /var/lock/

Here is my system configuration:
 linux 2.0.29
 mgetty 1.1.9
 modem: unknown thus i don't know how to find out the name of it (it
says V.17 FAX on the front)

The only thing I could think of after 15h work on it is that there is a
problem with my modem.

I would be very happy if anyone could help...


bye, Marcus
