get rid of dir.h

posix tty

../machine => machine

typo in attach routines; bug report 4.3BSD-tahoe/sys/34

merge common code from dmf and dmz drivers

correct uba reallocation on reset

4.3BSD release version

PASS8 affects only input, not output

revert to "sticky" baudrate except for portselector

try to make this sucker work! futz modem control to not look like

move carrier change code to line disciplines; make PORTSELECTOR
code and configuration consistent; change default speed to 9600
