It would require changes to 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. > quite a few programs to get fax receive to work based on RI > and it would not be a general 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.) > Still, it's a nice solution because it doesn't break the rules like > mgetty does.
