PK-900 Gateway Option Supplement
4
Note: With each station connected to your node, you’ll lose a “logical” channel. So,
if you have GUSERS set to 3, and three source stations have connected to three
destination stations through your node, they’ll take up six channels.
Users can instruct your Gateway to set up another connection either on the same
radio port or the other one if XGATEWAY is ON.
The requirements for Gateway connection are:
• If Port 1 is to be used, OPMODE must be set to PACKET, AMTOR or PACTOR.
(Port 2, of course, is always PACKET).
• The RADIO command must be set to enable the appropriate port(s).
• A modem supporting the appropriate port(s) and operating mode(s) must be
selected using the MODEM command.
• MYCALL must be set for each radio port to be used.
• MYGATE must have a callsign, but not the same one as MYCALL, MYALIAS, or
MYMAIL.
• GUSERS must be set to 1, 2 or 3.
Once connected to your Gateway, a user deals with a command processor similar to
that in a “regular” node. Command responses from your Gateway start with “+++”
to show that they’re coming from your Gateway command processor, rather than the
“***” from your TNC. (“+++” was chosen because the “+” is present in the AMTOR
character set while the other examples are not.)
Operation
Here’s what a user would see when using your Gateway as a packet node. In this
example, your MYGATE call is set to N7ML-7:
cmd:C N7ML-7
*** CONNECTED to N7ML-7
+++ N7ML Gateway. Type ? for help.
de N7ML-7 (B,C,D,J,L,N,S,?) >
The first line is the user’s connect request to your TNC. The second line is the connect
message from the user’s TNC. The third line is the greeting, and the fourth is the
command prompt from the Gateway. The user sends a question mark, ?, to obtain the
following help menu:
B(ye) Log off gateway
C(onnect) n Connect to station ’n’
C n STAY Stay connected to gateway when ’n’ disconnects
D(isconnect) Cancel a connect attempt
J(heard) Display stations heard
L(isten) Toggle monitoring
N(odes) Display nodes heard
S(end) Broadcast unproto (call CQ)
