There are several things here, that are contributing to your problem (words of
experience).  I will try to take them one at a time.

First, the most probable reason for  your "every other call connection" is the
modem is set to  give responses (ATQ0).  Therefore when you dial in, the modem
sends RING's to  the uugetty.  Uugetty interprets  this as someone's login and
may be waiting for a password.  This can be fixed by setting the modem to ATQ1
and saving  this with AT&W0.  Then add  the Q0 command  to the  entry for your
modem in /usr/lib/uucp/Dialers.  If your modem  has a reset  after loss of DTR
setting (most likely AT&D3)  this can  be used to reset the modem back to ATQ1
automatically after every call.

Second, it sound as though you may be missing the "-h" argument to the uugetty
command in /etc/inittab.  It should look something like this:

ta:1:respawn:/usr/lib/uucp/uugetty -h -r 3 -t 60 ttya 2400

And lastly, a combination of the modem's  automatic reset and a properly wired
modem cable should correct this last problem.

I hope this helps!!
