The program now lets you select and deselect features on a port-by-port
basis. The idea for this came from the 1989 Loma Prieta earthquake;
during the aftermath, BBS operators spent a lot of time manually
filtering traffic -- the features described in this section would have
made the job much simpler.
The features you can select are:
FORWARD EMERGENCY TRAFFIC ONLY
FORWARD NTS TRAFFIC
ACCEPT EMERGENCY TRAFFIC ONLY
ACCEPT NTS TRAFFIC
ALLOW E-MODE USERS ONLY
ALLOW CALL SIGN CHANGE
There are parameters for each one pertaining to the system and to the
port.
FORWARD EMERGENCY TRAFFIC ONLY
------------------------------
Only traffic defined by the EMERGENCY_TYPES parameter in PARMS.BB will
be forwarded. The applicable parm is FORWARD_EMERGENCY_ONLY.
ACCEPT EMERGENCY TRAFFIC ONLY
-----------------------------
Only traffic defined by the EMERGENCY_TYPES parameter in PARMS.BB will
be accepted. A normal user trying to send other traffic will be given
an error message; if a BBS tries to send other traffic, either the
message will be rejected or the station will be disconnected, depending
on the setting of the REJECT_ACTION in PARMS.BB. The applicable parm is
ACCEPT_EMERGENCY_ONLY
FORWARD NTS TRAFFIC
-------------------
NTS traffic will be forwarded. The applicable parm is FORWARD_NTS_OFF
ACCEPT NTS TRAFFIC
------------------
NTS traffic will be accepted. If this switch is off, then if a normal
user tries to send NTS traffic, he will be given an error message. If a
BBS tries to send NTS traffic, either the message will be rejected or
the station will be disconnected, depending on the setting of the
REJECT_ACTION in PARMS.BB The applicable parm is ACCEPT_NTS_OFF
ALLOW E-MODE USERS ONLY
-----------------------
Only users with the "E" flag in their user directory will be allowed to
use the BBS. The applicable parm is ALLOW_EMERGENCY_ONLY
ALLOW CALL SIGN CHANGE
----------------------
A user without the "E" flag in his user directory can change his call
sign once he is connected. The applicable parm in PARM.BB is
ALLOW_EMERGENCY_CHANGE. The purpose of this is to allow the use of
tactical addresses during an emergency. A typical scenario would be
as follows:
AA4RE is stationed at the Gilroy Emergency Operations Center. He
connects to the Emergency BBS but AA4RE is not an "E" mode user. The
BBS will propmt for a new callsign. He enters GILROY which is an "E"
mode user. This will then allow AA4RE to send and receive messages for
GILROY. Packets will have the proper ham callsign on them for
identification purposes.
The local ARES organizations (SF Bay Area) felt that this method was
preferable to using the tactical call sign as the call sign in the
TNC and having to beacon the ham callsign for ID purposes.
Setting the options
-------------------
Each of these options is controlled by a "system master switch" and a
"port switch". For an option to be effective, both the MASTER and
PORT switch must have the same value.
You can set these options directly in PARMS.BB or you can use the EP
command:
EP S -- Edit master switch list
EP x -- Edit port "x" switch list
You change switches by number. Specify the number by itself to invert
the setting of the switch. Specify the number followed by ON or 1 to
turn the switch on; specify the number followed by OFF or 0 to turn the
switch off.
There are parameters for each option for both the system and the port in
PARMS.BB. Its the same parameter in both places. You set the
parameter to either Y or N.
