8.2 Chase ioland
Utility
IOLAN+ peripheral daemon provides a client process with a
full-duplex and transparent interface to a server port of its
choice, via a pseudo-tty device. This presents a tty-like interface
to the application in much the same way as a serial port.
The daemon is primarily intended as an interface between
the client process and a printer, modem or some data
acquisition device. In the case of printers, it is
recommended that the LPD protocol is first assessed as a
suitable printing solution before the IOLAN+ daemon.
By default, the daemon will fork into two processes during
the start of a data transfer. The parent process will transfer
data from the client to the server while the child process will
transfer data from the server to the client. The parent also
handles all the control aspects of the client-server link. The
child process is normally terminated when the client process
closes the slave pseudo-tty unless the
-p option is used. In
this case, the child is created at startup time and remains.
If the daemon is started without any arguments it will try and
open the configuration file
/etc/ioland.cf which contains
instructions on which daemons to start, for which
peripherals, plus any optional arguments.
Alternatively, a single daemon can be started from the shell
with various arguments specified.
