PK-900 Gateway Option Supplement
6
whatever the user sends, goes to the destination station as data
instead of to the Gateway as a command.
Normally, when someone disconnects from your Gateway, no link will
remain. However, if a user adds the word STAY as the last argument in
a Connect request, (e.g., C callsign STAY), the user will remain
connected to your Gateway even after disconnecting from the destina-
tion station.
If the connect attempt to the destination station retries out or is busy,
your Gateway sends the user a Retry count exceeded or (Re-
mote) busy message, but remains connected to the user even if STAY
wasn’t entered.
D(isconnect) (To cancel a connect attempt.) Since the source station remains in the
Command mode until the connection to the destination station is
established, there’s no need for the user to wait for your Gateway to
cycle through a full number of retries to attempt a connection—the
user can send your Gateway a Disconnect request which cancels the
Connect request the same way it would in a TNC’s Command mode.
(The user stays connected to your Gateway even if STAY wasn’t used
in the original Connect command.) The Disconnect command may be
used at any time before the connection is established, regardless of any
preceding commands.
Once a connection is established and your Gateway is in the Converse
mode, the user can end the connection either by sending a B(ye)
command to the destination station if that station supports it, or by
issuing a Disconnect request to the user’s own TNC. If the user
disconnects from your Gateway this way, it will force your Gateway to
disconnect the destination station.
J(heard) Your Gateway sends its MHEARD list to the user. Your Gateway’s
DAYTIME and DAYSTAMP commands affect the display—the designators
“p1” and “p2” show the port on which each station was heard. A
maximum of eighteen stations are kept in the JHEARD list.
L(isten) The Gateway toggles monitoring on or off. The Gateway monitors
only on the radio port selected by the user (see PORT below), using the
appropriate operating mode.
N(odes) Your Gateway sends the user a list of nodes heard. The format is the
same as that of the JHEARD command, the difference being that a
callsign is put in the Nodes list only if the monitored packet was a UI
frame with a PID of CF (NET/ROM) or CD (IP). A maximum of ten
stations are kept in the Nodes list. You clear the nodes list and the
MHEARD list simultaneously with the same command, MHEARD %.
