Hi,

is there any reason why lpt.c uses spltty()?

For some frontends I maintain, this defeats the spltty/splserial split
of com.c... at least if implemented correctly (which it currently isn't, on
the lpt side).

I propose to use either splserial() or (to help serial performance on
machines where the lpt interupt is different from com interupts, like
ISA machines) a newly-created spllpt().
