The first problem I found was that descriptor 0 was being closed. This happens because the modem variable is set to 0 to indicate that it is not valid but there are not enough tests for the modem variable being 0. You can see where I have done this in the patch. Code in OpenModem() dups the modem descriptor if it is < 3. Once this happened the modem was always open and an incomming call would have getty and ppp reading the modem. Descriptor 1 is closed when the quit command was executed from a telnet connection. The next modem open returns descriptor 1 and this gets duped leaving the modem always open again. The modem was not being closed when the connection dropped or was closed from the other end. The UUCP lock was also not removed if the modem could not be opened.

unless you've adequately backed up your data first!
If any errors occur during this installation, you can see them
by toggling over to the alternate screen - type ALT-F2 to switch
over, ALT-F1 to switch back to the install screen. The debugging
output on the second screen may be very valuable to us in understanding
your bug report, so please be sure to take note of it when reporting
any failures in the installation! Thanks!
Menus and scrolling output windows may be traversed with the arrow
and Page Up/Page Down keys. To suspend the installation at any point,
hit ESC twice. Hitting TAB will move the focus to different controls.
If you've ever dealt with a DOS installation, you'll know how to deal
with this.

For more documentation on this system, it is recommended that you purchase
the 4.4BSD Document Set from O'Reilly Associates and the USENIX Association.
ISBN 1-56592-082-1 We have no connection with O'Reilly, we're just
