MESSAGES FROM THE TNC
60
EH?
This is the TNC's generalized "I don't understand" message. A dollar sign ($) is used to point to
the offending character. It will also appear if a required input item is missing, e.g.:
C KV7B V
$
EH?
In this example, the required callsign after the VIA option is missing. Most commands that re-
ceive an EH? error are ignored. In a few cases, part of the command may be accepted and
acted upon, as described under the message "Input ignored".
Enter Proper MYSelcal
Reminds you to enter the proper parameter prior to commanding a mode of operation which
requires it.
ENTER YOUR CALLSIGN=>
Type in your callsign. The TNC needs to know who you are to properly implement its protocol.
Your callsign will be placed in the MYALIAS, MYCALL, MYGATE, MYNODE and MYPBBS com-
mands to properly implement these different functions you will need to change each command
to a different call by using up to six alphanumerical characters and a substation id (SSID), if
desired. See the Commands section for further details about parameters of the callsign type
and specific commands listed above.
EEPROM BURN ERROR
The information written into the EEPROM by the PERM command did not verify properly.
EEPROM OVERFLOW
The EEPROM cannot store all of the data. This is normally caused by large amounts of text
stored in the text type parameters (BTEXT, CTEXT, NTEXT, PTEXT, WTEXT).
EXTERNAL MODEM CAN ONLY BE USED IN VHF-ONLY MODE
The particular optional modem installed inside the KAM unit can only be used when the HF val-
ue of MAXUSERS is set to zero.
EXTERNAL MODEM NOT SUPPORTED BY THIS SOFTWARE
This version of TNC software does not support the particular optional modem installed inside
the unit. Check with Kantronics on updates.
FRMR in progress
The TNC is connected but a protocol error has occurred. This is usually caused by two TNCs
having the same callsign entered. An improper implementation of the AX.25 protocol could
cause this this state to be entered. The TNC will attempt to resynchronize frame numbers with
the unit on the other end, although a disconnect may result. Connects are not valid in this
state and a disconnect command will start the disconnect process.
*** FRMR received
A frame reject packet has been received for an unknown reason. The information field of this
packet will display in hexadecimal value. This display may be useful in determining why the re-
ceiving station rejected your packet.
*** FRMR sent
Frame reject packet has been sent due to a detected error in protocol. Three bytes (6 hexade-
cimal characters) are displayed to assist in determining the reason for the reject.
