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