The most common PC hardware (separate dual UART + Centronics card)
often does.  The absence of a working interrupt line on some printer
ports has caused FreeBSD to support a polled-mode printer driver, but
without giving up its preference for the interrupt-mode driver.  I
don't see why the absence of a working RI on some hardware should
prevent us from experimenting with what might become a technically
cleaner solution.

Basically, only the getty needs to know about it.  This is just one
program (and in case you wanna receive fax and/or voice, you have to
teach your getty about it right now).  getty then acts as a dispatcher
that calls the appropriate receiver program (login, receivefax,
receivevoice, pppd, etc.)

Yep.

Never trust an operating system you don't have sources for. ;-)
