-.SH DESCRIPTION
-The \fBasc\fP character device driver currently handles the
-GI1904-based hand scanner (e.g. Trust Amiscan Grey).
-It uses DMA and interrupts. Input data from the scanner are
-buffered, up to 50 scanlines are buffered in the driver.
-.PP
-The device can operate at four different \fIresolutions\fP: 100, 200,
-300 and 400dpi. It produces a simple bitmap with the most significant bit
-at the left side. The driver can optionally output the famous and
-likely simple portable bitmap file format pbm(5) by Jef
-Poskanzer. Thus the scans can easily processed by any graphic package
-around (xpaint, xv, xli only to name some of them ...).
-.PP
-The \fIwidth\fP of the output bitmap is fixed as given by the
-resolution value. However, the \fIheight\fP of the bitmap must be
-supplied in \fIpnm\fP mode since the driver must know at what time the
-'end-of-file' shall be reached. The default is to produce a
-square image, i.e. \fIheight=width\fP. With this feature you are able to
-directly copy the scanner output into a pbm file whith cat(1).  Of
-course you can obtain a similar effect by using dd(1) with the driver
-in \fIraw\fP mode.
-.PP
-The \fIgraymap\fP output mode is not yet implemented into the driver.
-It is even questionable if external programs would not do this job
-better thereby not counting to the size of the kernel. Even though, I
-do not know of tools which produce a graymap from a halftone bitmap.
-.SH IOCTL REQUESTS
-The ioctl requests that are served by \fBasc\fP are listed below.
-There is a utility, called sasc(1), that provides access to these
-requests from within shell.

+.Sh SYNOPSIS
+.Cd "device asc0 at isa? port IO_ASC1 tty drq 3 irq 10 vector ascintr"
+.Sh DESCRIPTION
+The
+.Nm
+character device driver currently handles the
+.Tn GI1904 Ns -based
+hand scanner (e.g. Trust Amiscan Grey).
+It uses DMA and interrupts. 
+Up to 50 lines of scanned input data are buffered in the driver.
+.Pp
+The device can operate at four different resolutions: 100, 200, 300
+and 400 dots per inch. It produces a simple bitmap with the most
+significant bit at the left side.  The driver can optionally output
+the simple portable bitmap file format
+.Xr pbm 5 ;
+thus the scans can easily processed by most graphics packages.
+.Pp
+The width of the output bitmap is fixed as given by the
+resolution value.  However, the height of the bitmap must be
+supplied when in
+.Xr pbm 5
+mode, since the driver must know at what time the
+`end-of-file' shall be reached.  The default is to produce a
+square image; i.e., height equals width.
+With this feature one is able to
+directly copy the scanner output into a
+.Xr pbm 5
+file using
+.Xr cat 1 .
+One can obtain a similar effect by using
+.Xr dd 1
+with the driver
+in raw mode.
+.Sh IOCTLS
+The
+.Xr ioctl 2
+commands applicable to
+.Nm
+are listed below.
+The
+.Xr sasc 1
+provides user-level access to these commands.
+.Bl -tag -width "ASC_GHEIGHT"
+.It Dv ASC_GRES
+.Pq Li int
 Get current resolution in dots per inch (dpi).
-.TP
-ASC_GWIDTH int
+.It Dv ASC_GWIDTH
+.Pq Li int
 Get current width of the bitmap in pixels.
-.TP
-ASC_SHEIGHT int
-Set the \fIheight\fP of the bitmap in \fIpnm\fP mode. This is actually
+.It Dv ASC_SHEIGHT
+.Pq Li int
+Set the height of the bitmap in 
+.Xr pbm 5
+mode.  This is actually
 a limit on the amount of lines scannable after the first read
-operation. When the limit is reached read will return 0. However, the
-device is turned off only when a close is performed (either
-explicitely or implicitely on exit of the calling process).
-.TP
-ASC_GHEIGHT int
+operation.  When the limit is reached, read will return 0. However, the
+device is turned off only when the last open file descriptor is closed.
+.It Dv ASC_GHEIGHT
+.Pq Li int
 Get the current height of the bitmap.
-.TP
-ASC_SBLEN int
+.It Dv ASC_SBLEN
+.Pq Li int
 Set the length of the buffer used internally to do the DMA transfer.
 The buffer length is supplied in lines of the bitmap. Since the buffer
-size limit is (currently) 0x3000 bytes the maximum number of lines
-allowed will vary with the width of each line. This upper limit is
-checked before it overwrites the current value and pases an ENOMEM in
-the \fBerrno\fP variable. However, since the bitmap width can change
-after a buffer length was selected a read request may fail with ENOMEM
-if the buffer length turns out too high. It is generally wise to
-choose long buffers rather than go save in order to obtain better
-output.
-.TP
-ASC_GBLEN int
+size limit is (currently) 0x3000 bytes, the maximum number of lines
+allowed will vary with the width of each line.  An
+.Er ENOMEM
+error is returned if the requested length would exceed this limit.
+.It Dv ASC_GBLEN
+.Pq Li int
 Get the current buffer length in lines.
-.TP
-ASC_SBTIME int
+.It Dv ASC_SBTIME
+.Pq Li int
 Set the timeout for the completion of reading one buffer. Since a
 handy scanner is a human/computer interface timeout values are usually
-higher than those of a flat scanner. Default is 15 seconds. After
-timeout is reached the read operation will fail with EBUSY. Note that
-the timeout timer starts anew for each buffer to be read and thus does
-not cause you to scan faster for longer images. BLEN/BTIME is similar
-as MIN/TIME in termios(4).
-.TP
-ASC_GBTIME int
+higher than those of a flat scanner; the default is 15 seconds.  After
+timeout is reached the read operation will fail with 
+.Er EBUSY .
+Note that
+the timeout timer starts anew for each buffer to be read and thus 
+reducing it does not result in faster scans for longer images.
+.It Dv ASC_GBTIME
+.Pq Li int
 Get the current buffer timeout.
-.PP
-All ioctl requests that modify a parameter except ASC_SBTIME do not
-have an effect on an ongoing scan process, i.e. after the first read
-request that follows open. You must close the device and open it again
-for the new selections to take effect. Consequently, the selections
-are not reset when you close or open the device.
-.PP

+All
+.Fn ioctl
+requests that modify a parameter except
+.Dv ASC_SBTIME
+do not have an effect on an ongoing scan process.  The user must close
+the device and open it again for the new selections to take effect.
+Consequently, the selections are 
+.Em not
+reset when the device is opened or closed.
+.Pp
 Similarily, requests that read a value do not report the value that is
-used for the ongoing scan process. The values needed during the scan
-process are saved when it starts and thus are not accessed by ioctl
+used for the ongoing scan process.  The values needed during the scan
+process are saved when it starts and thus are not accessed by 
+.Fn ioctl
 requests.
-.PP
-The BTIME value does, however, have an immediate effect on the ongoing
-scan. Thus the timeout can for example be set to long until the user
-starts scanning.  It can then be set to a short amount to react
-(nearly) immediately when the user stops. Note that the user should be
-left time to at least fill one buffer without having to haste.
-.PP
-Note that the \fIpbm\fP versus \fIraw\fP mode selection is done by the
-minor number not by ioctl requests. In \fIraw\fP mode the selected

+The
+.Dv ASC_SBTIME
+value does, however, have an immediate effect on the ongoing scan.
+Thus the timeout can, for example, be set to a large value until the
+user starts scanning, and then set to a small value to react
+(nearly) immediately when the user stops.
+.Pp
+Note that the
+.Xr pbm 5
+versus raw mode selection is done by the
+minor number, not by
+.Fn ioctl
+requests.  In raw mode, the selected
 height of the bitmap will have no effect.
