My PPP setup broke when I upgraded my Mac IIx to NetBSD 1.3. Chat complains
of "Can't restore terminal parameters: Invalid argument". I'm connecting
through a modem on /dev/tty00 (modem port). Anybody else encountered this?
I can send more information if necessary to anybody who might have an idea.
