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. 5*46869Sbostic 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. 15*46869Sbostic 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 . 18*46869Sbostic 19*46869Sbostic 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. 26*46869Sbostic 27*46869SbosticBill Sebok Princeton University, Astrophysics 28*46869Sbostic{allegra,akgua,burl,cbosgd,decvax,ihnp4,noao,princeton,vax135}!astrovax!wls 29
