When a printer is switched from 37a mode to another, this change will only take effect 38the next time the device is opened. 39.Pp 40Extended mode is anything the parallel port interface can support. 41For an 42ECP/ISA parallel port, it may be FIFO+DMA or ECP. 43.Pp 44The following command line options are supported: 45.Bl -tag -width indent 46.It Fl i 47Turn on interrupt-driven mode. 48.It Fl p 49Turn on polled mode. 50.It Fl e 51Turn on extended mode. 52.It Fl s 53Turn on standard mode, i.e. turn off extended mode. 54.It Fl d Ar dev 55Set the mode of the printer device specified by 56.Ar dev . 57The default value for 58.Ar dev 59is 60.Pa /dev/lpt0 . 61.El 62.Pp 63One of 64.Fl i 65, 66.Fl p 67or 68.Fl e 69must be specified. 70.Pp 71.Sh FILES 72.Bl -tag -width /sys/i386/conf/GENERIC -compact 73.It Pa /dev/lpt? 74printer devices 75.It Pa /dev/lpctl? 76printer control devices 77.It Pa /sys/i386/conf/GENERIC 78kernel configuration file 79.El 80.Sh BUGS 81Sure to be some. 82.Sh "SEE ALSO" 83.Xr lpt 4 84.Sh AUTHORS 85.An Geoffrey M.
