Stopping incoming faxes with mgetty - Redux

Hey,   I got a couple of immediate responses and realize my request was
somewhat short.  I will give it in three sections Problem, What I have
done, Documentation. Problem:    I use mgetty on two modem ports to allow
remote logins.  mgetty works well to keep the connections clean, however
I get unsolicitated faxes to these modems.  I want to continue using
mgetty, but want to block the incoming faxes. What I have done:   I tried
putting the -D option on mgetty in inittab, then running kill -HUP 1 so
init rereads the inittab, then killed the /sbin/mgetty ttyS1 inorder to
have the process respawned with the -D option.  I then tried sending a
fax to the ttyS1 line and it was accepted.  Surprise!    I went back to
the books and tried to approach the problem in a different way.  I edited
/etc/mgetty+sendfax/mgetty.config with the following two lines: port
ttyS1data-only y   These files are read when mgetty is invoked and my
intent was to identify ttyS1 as a data only (e.g. no fax) line. I tested
it by sending a fax and it also was accepted. Documentation: Here are two
listings.  The first a data connection, the second a fax connection (with
the above -D and data-only entries active) I changed the numbers to be
xxx xxx xxxx for this email.  Notice mgetty sees teh difference between a
data connection and a fax connection. 05/02 21:04:12 yS1  mdm_send: 'AT'
