One Nov 23, a change was made to /usr/src/sys/kern/tty.c by bde to do the following: o Handle c_ispeed = 0 to c_ispeed = c_ospeed conversion here instead of in drivers and fix drivers that write to tp->t_termios. When I backed out this change, my Tk/Tcl programs began working as normal. I reverted by to tty.c v1.107. My guess is that I'm using a driver that needs to be fixed per the comment above. Unfortunately, I don't know which one... Anyway, the system is now working much better. Thanks to all who responded!
