Keyword Reference
Below the keywords which may appear in a 'vlc.setup' file are shown in tabular form.
COMMENT
The COMMENT keyword defines an identification string which should describe the
purpose and the revision of this configuration file. A message with the string defined with
COMMENT is listed in the event log when the software starts. There should be exactly
one COMMENT definition in each 'vlc.setup' configuration file. It usually appears at the
very beginning of the file, however this is not a must.
Syntax:
COMMENT " Arbitrary String "
Example:
COMMENT "BDRT4 Setup, 11.May 2001"
PORT
The PORT keyword introduces an interface port, which all definitions following the
PORT definition refer to.
Syntax:
PORT Interface-Name
Interface-Name is the name one of the serial ports installed at the computer
or the special name "null". The latter is used in conjunction with the
"Logical" communication protocol for so called "logical devices" which exist
in the software without a counterpart in the real world.
Example:
PORT ttyS11
For each interface the software uses, there must be one PORT definition. PROTOCOL,
DEVICE or IDLE definitions following the PORT definition automatically refer to it.
PROTOCOL The PROTOCOL keyword defines a communication protocol to be used with the PORT
definition it follows. There must be exactly one PROTOCOL definition for each PORT. A
port's communication protocol must be defined prior to any DEVICE definitions.
The set of communication protocols which are available on a certain VLC/M&C computer
may vary. Type '
ls protocols/
' at the shell prompt in the home directory of the
software to get a list of protocols which are actually available.
Syntax:
PROTOCOL Protocol-Name
Example:
PROTOCOL NAIS-FPx
There must be exactly one PROTOCOL specification following each PORT definition.
The special protocol 'Logical' must be used, if the PORT is named 'null'.
DEVICE
The DEVICE keyword attaches a device to the port defined above. Usually you will
attach one device to a port. Some protocols allow multiple devices being controlled
through a single interface. In such a case you can attach more than one device to a port.
Syntax:
DEVICE Device-Name IS Driver-Name
Device-Name is a short and pregnant name you choose to uniquely identify
the device in the VLC/M&C. Device names must not be used twice. Device
names should not be longer than 11 characters as they are cut to this length
in event log messages.
Driver-Name selects the device driver the software shall use for this device.
