I'll add them if I can. I've been considering adding the following to the tty driver. 1) Sending a break by setting Baud to 0. (Should have been there in the first place.) 2) Sending a SIGHUP on loss of DTR (or what ever the right control signal is.) 3) Some way to detect an incomming break from a user program. I could take the time to look it up, but I thought I'd just ask "how does UNIX do this?" and see if any one already knows. 4) "Software" control of hardware handshaking by flags in the tty minor device number. Any thing else I should add? -Phil

Hardware flow control compatible with a Telebit modem under uucp would be a neat deal... or has Dave hacked this in at home already? :-) Bdale

It is a configure option in /usr/include/minix/config.h. I spent quite a while trying to make sure that it worked. I even used a break out box to control the hareware signals to make sure that things stopped and restarted again with the hardware control lines. That is why I was thinking about making minor device number controled so some lines could have hardware flow control and others could run without it. --Phil
