+
+.SH NAME
+lptcontrol - a utility for manipulating the lpt printer driver.
+.SH SYNOPSIS
+.na
+.B lptcontrol
+.RB [options]
+.SH DESCRIPTION
+The
+.B lptcontrol
+command is used to set either the interrupt-driven or polling mode
+of individual lpt devices. When a printer is switched between
+interrupt-driven and polled mode, this change will only take effect
+the next time the device is opened.
+.SH OPTIONS
+.TP
+The following command line options are supported.
+.TP
+.B \-i
+Turns on interrupt-driven mode.
+.TP
+.B \-p
+Turns on polled mode.
+.TP
+.BI "\-f\ " file
+Sets the mode of the printer device specified by
+.I file.
+The default value for
+.I file
+is
+.I /dev/lpt0
+.TP
+One of
+.B \-i
+or
+.B \-p
+must be specified.
+.PP
+.SH FILES
+/dev/lpt?
+.PP
+.SH BUGS
+If the port to be controlled does not have a printer connected and
+on-line, then lptcontrol will not be able to open the port in question
+for performing ioctl's and will fail.
+.sp
+Sure to be others.
