1*46869SbosticWe started to use uucp after the dialin lines had been in place for a while.
2*46869SbosticIt would have been very unpopular here to remove one of lines from public use
3*46869Sbosticto let uucp dial out.  The first version of these changes ran here early in
4*46869Sbostic1983.

6*46869SbosticHaving this ability is very useful way to make full use of your modems. For
7*46869Sbosticone thing, I can smile when a neighoring site complains that their one dialer
8*46869Sbosticis tied up from news backed up to one of their neighbors which has been down
9*46869Sbosticfor a while and has just come back up. For another thing some of our neighbors
10*46869Sbosticseem to be reachable better by some modems than by others.  For example, I can
11*46869Sbosticonly reach rocky2 with a Racal Vadic.  I can only reach akgua, burl, and
12*46869Sbosticsjuvax with a Hayes.  When our 2400 baud modem arrives so I can make special
13*46869Sbosticnote of that --- and I don't have to buy two 2400 baud modems to have two-way
14*46869Sbostic2400 baud capability.

16*46869SbosticThe key to this is a program is provided in the file acucntrl.c .  This should
17*46869Sbosticbe installed suid to root in the file /usr/lib/uucp/acucntrl .

20*46869Sbosticuucp notes:
21*46869SbosticThe 3rd field of the L-devices file should contain "inout"  for all devices
22*46869Sbosticintended for dialin/out use.  Devices without the "inout" specification will
23*46869Sbosticbe used like before: for dialout only.
24*46869Sbostic
25*46869SbosticGood luck.  I want to never go back to reserving modems for dialout.
