1We started to use uucp after the dialin lines had been in place for a while. 2It would have been very unpopular here to remove one of lines from public use 3to let uucp dial out. The first version of these changes ran here early in 41983. 5 6Having this ability is very useful way to make full use of your modems. For 7one thing, I can smile when a neighoring site complains that their one dialer 8is tied up from news backed up to one of their neighbors which has been down 9for a while and has just come back up. For another thing some of our neighbors 10seem to be reachable better by some modems than by others. For example, I can 11only reach rocky2 with a Racal Vadic. I can only reach akgua, burl, and 12sjuvax with a Hayes. When our 2400 baud modem arrives so I can make special 13note of that --- and I don't have to buy two 2400 baud modems to have two-way 142400 baud capability. 15 16The key to this is a program is provided in the file acucntrl.c . This should 17be installed suid to root in the file /usr/lib/uucp/acucntrl . 18 19 20uucp notes: 21The 3rd field of the L-devices file should contain "inout" for all devices 22intended for dialin/out use. Devices without the "inout" specification will 23be used like before: for dialout only. 24 25Good luck. I want to never go back to reserving modems for dialout. 26 27Bill Sebok Princeton University, Astrophysics 28{allegra,akgua,burl,cbosgd,decvax,ihnp4,noao,princeton,vax135}!astrovax!wls 29
