Instruction manual

This command transmits the entered characters to the GPS port. This command is used to send
initializing command(s) to the GPS. The content cannot be stored in memory but some GPS units
will have a memory feature (This is mainly to conserve space in the RAM which is very limited in
this unit). The main-loop process is stopped while the data is transmitted to the GPS. Too long or
too frequent transmission of the data may cause problems with the function of the TNC.

6 Operational mode
This firmware contains the following operational modes:
l command mode
l converse mode
l KISS mode
6-1 Command mode
As mentioned in 2-1, the operational mode is usually “connect mode”. The “cmd:” prompt
appears when it is in the command mode. If it does not appear, use CR or return or Enter key to
display it on the screen.
6-2 Converse mode
As briefly mentioned in 2-1, this is the mode to send typed data as a packet. By using the
CONVERSE or K command from the command mode, it switches to the Converse mode. The
TNC also enters the converse mode when you connect from your station to another station. To
return to command mode from the converse mode, use Ctrl+C.
6-2-1 Converse command
abbrev. CONV default: none parameter: none
example: CONV
This is to change the mode to CONVERSE mode. The typed data in converse mode will be sent
out as a packet. To return to command mode from the converse mode, use Ctrl+C keys.
6-2-2 K command
Abbrev. K default: none parameter: none
Example: K
This is same as the Converse command. Since this change is required very often, the K is made
available as a shortcut.
6-3 KISS mode
This is a special mode to enable protocol control from the PC. Specific KISS mode software is
necessary. The EJ-41U is compatible with KISS but in very limited manner. We do not
recommend the use of this mode.
