I was about to trash a modem because the HDLC and buffer overflows were
grinding it to halt --- or just about.  I switch slots, changed the modem
out with and old 28.8, and so forth.


Eventually I discovered some really old stuff about sio.c which
suggested this:

   	cp4ticks = speed / 10 / hz * 4;

be changed to this.

   	cp4ticks = speed / 10 / hz * 40;

and everything worked like a charm

So I am wondering why this hasn't been changed since it seems to be
necessary for proper operation of just about the only non-winmodem
available.
