+.Sh NAME
+.Nm loadfont
+.Nd is used to load fonts into EGA or VGA boards for use by the 'pcvt' video
+driver.
+.Sh SYNOPSIS
+.Nm loadfont
+.Op Fl c Ar charsetno
+.Op Fl f Ar fontfilename
+.Op Fl i
+.Sh DESCRIPTION
+The
+.Nm loadfont
+utility is used to load fonts needed for proper operation of the pcvt
+VT220 driver on EGA and VGA boards into the font ram of this boards.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl c
+Specifies the slot, the font is to load into. EGA boards have four 
+slots and VGA boards have eight slots available for downloading fonts.
+.It Fl f
+Specifies the file which contains the font to be downloaded.
+.It Fl i
+Gives information what type(s) of font do currently reside in which slot.
+This is also the default behaviour if no options are specified on the commandline.
+.El
+.Pp
+This utility is used only on EGA and VGA boards, as MDA, HCG and CGA boards
+do not have downloadable charactersets available.
+.Sh FILES
+Unless otherwise specified in the Makefile, the following fontfiles are
+available for the pcvt 2.0 distribution:
+
+.nf
+/usr/share/misc/vgafonts/vt220l.808:	8x8  IBM II font
+/usr/share/misc/vgafonts/vt220h.808:	8x8  Extension font
+/usr/share/misc/vgafonts/vt220l.810:	8x10 IBM II font
+/usr/share/misc/vgafonts/vt220h.810:	8x10 Extension font
+/usr/share/misc/vgafonts/vt220l.814:	8x14 IBM II font
+/usr/share/misc/vgafonts/vt220h.814:	8x14 Extension font
+/usr/share/misc/vgafonts/vt220l.816:	8x16 IBM II font
+/usr/share/misc/vgafonts/vt220h.816:	8x16 Extension font
+.fi
+.Sh EXAMPLES
+The command
+.Dq Li loadfont -c0 -f/usr/share/misc/vgafonts/vt220l.816
+loads a 8x16 font containing the standard IBM characterset II into font slot
+0 on a VGA or EGA board.
+.Sh BUGS
+No known bugs
+.Sh SEE ALSO
