Accessing a device file?

[David Kastrup]

Hi,

I want to create a midi input process for Emacs.  It will just open
/dev/midi1 and read stuff from it, using process filters to work on it.

Very simple conceptually.  And it would appear that something like
make-serial-process would perfectly fit the bill.

Indeed, something like
(make-serial-process :port "/dev/midi1" :speed nil)
appears to do the trick, creating a buffer named "/dev/midi1" and
delivering events there.

However, what's the deal with requiring :speed nil ?  It would appear
that the interface is cleaner without requiring this (actually
specifying a non-nil speed will fail trying to set the appropriate tty
setting).
