slattach is for slip (Serial Line IP, the precursor to ppp). I don't
understand why Marc said it would do what you want. Perhaps you don't
have slip configured in your kernel and that's the error about the line
discipline.

What are you trying to do here? Use a serial line from a program
that does not understand how to set the baud rate?
