is enabled and so that the printer system language supports reporting
and job control (PJL or PostScript, for instance).
In this mode the Convert Box may be used in a DCPS (DECPrint
Supervisor) environment provided that the printer connected to the
parallel port is set to the PostScript system language.
The Autosensing mode
In this mode, the Convert Box detects whether the data received
through the serial input port is a DEC PPL3 job or a PostScript job.
When the Convert Box is idle for a given time-out, the first data string
is analyzed. If the string is made of "%!PS-Adobe", the data is
considered as PostScript data, therefore no data conversion and
interpretation take place. If the string is not made of the above, data
conversion from DEC PPL3 to PCL5 is active.
The given time-out is 20 seconds by default and can be modified by
software configuration.
The Hex Dump mode
In this mode, all data received from the input serial port is printed in
Hexadecimal representation on the printer connected to the parallel
port. This mode allows the user to analyze the data sent by the host to
the convert box .
