APPENDIX D
SOFTWARE COMMANDS
APX D-6
NULLS (0-255)
The nulls command, where n is equal to the number of nulls to send
after either a carriage return <CR> or a line feed <LF>. Factory
default = O.
PACKleng (1-1010)
This command defines the length of the data packet in bytes.
Factory default = 1010.
PACKMON (on/off)
Places the ESTeem in the packet monitor mode. Factory default =
OFF.
PLC_MAST (on/off)
The programmable logic controller (PLC) command.
ON: When enabled, the ESTeem modem will identify the desired
route from the master PLC message. The ESTeem modem
will only identify the PLC master route if the master command
is enabled in the PLC.
OFF: The ESTeem modem will be configured as to interface to
a slave PLC.
Factory default = OFF.
POLLed (on/off)
When enabled the ESTeem will only transmit the contents of its
internal transmit buffer when it receives an ENQ (hex 5) from a
polling ESTeem. During non polled times the ESTeem transmit
buffer will be continuously updated from data being received by the
RS-232C/422 port. This software feature was developed for
interfacing the ESTeem to output devices without flow control that
are to be polled from a master device.
ON: Enabled will transmit the contents of its transmit buffer when a
ENQ (hex 5) is received.
OFF: Disabled.
Factory default = OFF.
PREfix (1-255)
This is the character that precedes the formatted message (See
Messform). It may be given any value from 1-255. If a O is used,
then there will be no prefix value. This character is generally used to
flag the users software that an ESTeem message follows.
Factory default = 0.
PROGRAM (0-254,0-254,0-254,0-255)
This command is used to remote program another ESTeem unit.
Example PROG: 10 (Unit 10 is the address of the remote unit).
When a connection has been made with the remote ESTeem the
RPG: prompt will appear. Showing you are now in the command
prompt of the remote modem. See REMPROG.
PRompt (on/off)
The prompt enable command.
ON: The prompt responses are enabled. These are the prompts for
Converse or Trans Mode that are normally output from the
RS-232C serial port by the ESTeem.
Factory default = ON.
PROTOCol (on/off)
The protocol command when interfacing the ESTeem to a
mainframe computer. This command allows the ESTeem to be
connected to computers using the ENQ/ACK type of protocol. The
ENQ/ACK characters are user definable by the PROTORX and
PROTOTX commands.
Factory default = OFF.
PROTORx (0-255)
The enquiry character received by the ESTeem when connected to a
mainframe computer. The value in decimal specifies an ASCII
character used to signal the ESTeem when to send the- PROTOTx
ASCII character.
Factory default = 5.
PROTOTx (0-255)
The ACK character transmitted by the ESTeem when connected to
a mainframe computer, after receiving the PROTORx inquiry ASCII
character from the mainframe. The value in decimal specifies an
ASCII character used to signal the mainframe, or acknowledge the
mainframe, that the ESTeem has received a PROTORx ASCII
character. Factory default = 6.
RADio (on/off)
The radio transmitter enable command. The ESTeem radio
transmitter will cycle on and off when enabled for tuning and
adjusting procedures. The factory default value is OFF.
