I just came across a 'null modem cable' that connects DCD to: nothing! It connects DTR to DSR but _not_ to DCD... other than that the wiring appears to be normal. Well, so i hacked an `altpin' flag into sio that lets me swap the functions of DSR and DCD. (Anyone thinks that would be worth cleaning up and send-pr'ing?) And a happy new year to everyone... -- Juergen Lock (remove dot foo from address to reply) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
