ESTEEM SYSTEM STATUS MESSAGE TABLE
Listed below are the ESTeem System Status Messages and their definitions. To receive these messages, TYPSYSTEM must be ON (See
APPENDIX E, DEFINITIONS). All System Status Messages have a bell (O7H or CTRL G) preceding the message except when Messform is ON.
If Messform = OFF Line A will be displayed. If Messform = ON Line B will be displayed.
1. A "CONNECTED TO XX"
B SSO1-xx
This message is caused by either receiving a reply from a Log
On Packet, receiving a Log On Packet, or by typing LINK when
connected and in the COMMAND MODE. XX is the address
of the modem connected to.
2. A "DISCONNECTED FROM XX"
B SSO2-xx
Tells that you have been disconnected from the device you
were originally connected to (xx is unit address).
3. A "DESTINATION CONNECTED TO ANOTHERNODE"
B SSO3
This message occurs while trying to log to a node that is
already logged to another node. The destination node sends a
Node Busy Packet which, when received, causes this message
to be displayed. The ESTeem remains in the COMMAND
mode.
4. A "LINK BUSY"
B SSO4
This message is caused by receiving a Node Busy Packet from
the destination node. Any further packet transmission is
disabled until a Node Ready Packet is received from the
destination node.
5. A "PACKET REJECTED"
B SSO5
This message is caused by an invalid sequence number
between transmit and receive. This could happen if the data
somehow was modified during transmission. The normal
recovery from this message is to reconnect. This will
synchronize the sequence numbers between the transmit and
sending ESTeems. This message usually indicates a soft
failure in the link.
6. A "DESTINATION NODE RESET"
B SSO6
This message is caused by the destination node being reset
(power up, down, etc.), and the other node continues to send
data. The normal recovery from this message is to reconnect.
This will synchronize the sequence numbers between the
transmit and sending ESTeems. This message usually
indicates a soft failure in the link.
7. A "LINK DOWN"
B SSO7
This message occurs after sending the last retry data packet
and receiving no response from the destination node. This
message usually indicates a hard failure -i.e. destination node
not energized, wrong baud rate, (not compatible between units)
improper transmit/receive frequency between nodes, etc.
8. A "ADDRESS USED AS SOURCE!"
B SSO8
The Connect Address you gave is the same as your Unit
Address.
9. A "CURRENTLY NOT CONNECTED!"
B SSO9
The Disconnect was issued while the modem was not
connected to another modem or when LINK is typed in the
COMMAND MODE when you are not connected.
1O. A "ECHO IS ALREADY Disabled"
B SS1O
This message is displayed if ECHO is disabled while enabling
PASSWORD.
11. A "PASSWORD IS ENABLED"
B SS11
This message is displayed if PASSWORD is enabled while
disabling ECHO. All System Status Messages have a bell
(O7H/CNTLG) preceding the message except when Messform
is ON.
12. A "SECURITY IS ALREADY ENABLED!"
B SS12
Security ON command was issued while security was currently
enabled.
13. A "SECURITY IS ALREADY DISABLED"
B SS13
Security OFF command was issued while security was
currently Disabled.
14. A "ENTER SECURITY VALUE"
B SS14
The ESTeem will prompt for a security value after Security On
is issued. The value may be O-65535.
