APPENDIX D
SOFTWARE COMMANDS
APX D-2
DEFINITIONS
Listed below are the definitions of the ESTeem software commands listed in alphabetical order:
A_BADD (ON/OFF)
This function enables an addressing table for Allen Bradley half
duplex equipment. For further details reference the EST
Engineering Report on Allen Bradley controller interfacing. Factory
default = OFF.
A_BCTRL
This function enables the Allen Bradley controller protocol. For
further details reference the EST Engineering Report on Allen
Bradley controller interfacing. Factory default = OFF.
A_BPOLET (1-255)
This command defines the rate at which the ESTeem modem sends
Allen Bradley half duplex poll messages. For further details
reference the EST Engineering Report on Allen Bradley controller
interfacing.
Factory default = 30.
ADDress (0-255)
The command defines the ESTeem source address. The default
value is whatever address has been stored in nonvolatile
memory. Addresses 0 to 254 are usable for unit addressing.
Address 254 is used for Self Test. Address 255 is used for
GLOBAL.
ALTEREtr (0-255)
This command specifies the number of retries to establish a link
under the ALTEROUT command. This command is independent to
the RETRY command.
Factory default = 2. NOTE: When ALTERROUT = ON, the RETRY
variable determines how many times the ESTeem will cycle through
the ALTEROUT table before displaying the "Link Is Down"
message.
ALTEROUT (on/off)
This command allows the user to define four alternate routes. When
this software switch is enabled the ESTeem will prompt the user for
four addition modem addresses or destinations. It is noted that a
destination using repeater paths can be used. If the modem is
unable to connect to the specific unit addressed or "DESTINATION
CONNECTED TO ANOTHER NODE" is encountered the modem
will try to connect using an alternate route. The modem will start
route selection with the last route used or the SETCONN
variable. The ALTERETR command will determine the number of
tries the ESTeem will attempt to connect before it switches to the
next route defined in the table. Factory default = OFF.
AUtolf (on/off)
This command enables the auto line feed sent to the terminal after
each carriage return. Factory default = ON.
BKONdel (on/off)
This command when enabled echoes to the terminal the [backspace
- space - backspace -delete] sequence when the DELETE character
is entered. When disabled the [\] is echoed to the terminal when the
DELETE character is entered. Factory default = ON.
CARBsy (1-255)
This command defines the carrier busy delay in TICS. One TIC
equals 16.67 milliseconds.
COMMand (0-255)
This command specifics the value in decimal specifying an ASCII
character used to return the ESTeem to COMMAND MODE. If the
COMMAND variable is sent when in the COMMAND MODE any
pending radio transmissions are terminated and the RS-232C
receive buffers are cleared. Factory default = $O3 (Hex) or CTRL-C.
CONNect (r1,r2,r3,da)
This command performs the CONNECT to a destination ESTeem.
This function supports a direct connect or a connect through a
maximum of three repeater nodes. The default value is whatever
address has been stored by the SETCONN COMMAND.
r1 = ESTeem address (0 to 253) of repeater 1.
r2 = ESTeem address (0 to 253) of repeater 2.
r3 = ESTeem address (0 to 253) of repeater 3.
da = Destination address (0 to 255).
CONVers
The execution of this command causes an immediate exit from
COMMAND MODE into CONVERSE MODE.
COPright
The execution of this command causes the copyright information to
be printed.
DISACK (on/off)
This command when enabled instructs the modem to disable the
acknowledgement request on the information packet. This is used
when the designation device will respond with its own
acknowledgement.
Factory default = OFF.
