DESCRIPTION
Dossrv is a file server that interprets DOS file systems. A
single instance of dossrv can provide access to multiple DOS
disks simultaneously.
Dossrv posts a file descriptor named service (default dos)
in the /srv directory. To access the DOS file system on a
device, use mount with the spec argument (see bind(1)) the
name of the file holding raw DOS file system, typically the
disk. If spec is undefined in the mount, dossrv will use
file as the default name for the device holding the DOS sys-
tem.
Normally dossrv creates a pipe to act as the communications
channel between itself and its clients. The -s flag
instructs dossrv to use its standard input and output
instead. The kernels use this if they are booting from a
DOS disk. This flag also prevents the creation of an
explicit service file in /srv.
The -v flag causes verbose output for debugging.
The shell script a: contains
unmount /n/a: >[2] /dev/null
mount -c /srv/dos /n/a: /dev/fd0disk
and is therefore a shorthand for mounting a floppy disk in
drive A. The scripts b: and c: are similar.
9660srv is identical to dossrv in specification, except that
it interprets ISO9660 CD-ROM file systems instead of DOS
file systems.

If the floppy drive has an ejection motor, eject will spit
out the floppy from drive n, default 0.
