If LA-120's jog DTR when they *transmit* a ^D I'd call it a bug. Terminals like TTY-43's did lower DTR when they *received* ^D's, but transmitted them without a wimper. The V7 UNIX tty driver (ah, the old days!) would inhibit echo of the ^D when in COOKED mode, allowing the hoards of TTY's around Bell to send ^D's with impunity. The much-maligned 4.1BSD tty driver preserves this tradition. CBREAK and RAW mode are another matter--^D's are echoed just fine in these modes. Could it be that you are in one of these modes when you sign off? Or (gasp) half-duplex? Or is the LA-120 that brain-damaged? -Ed Hall edhall@rand-unix decvax!randvax!edhall

From: Ron Natalie <ron@brl-vgr> Yeah, we actually had those teletypes with the ORIGINATE/ANSWER modem, a telephone dial, and the funky out of service light built into the ASR33 to the right of the keyboard. Control-D hung up the modem. Great fun to send them to a user's terminal when he was logged in via one. Fortunately the model 37 doesn't do this or else the all the NROFF hackers would have insisted on a new EOF character a long time ago. -Ron
