SENDING MESSAGES on XOBBS...The 'S' Command
Messages to 'local' stations
S Call letters. For example: S W3ABC sends a message to W3ABC
on this BBS. It will not be forwarded to any other BBS and must
be read by W3ABC on this BBS.
Messages to be Forwarded to another BBS
S ToCall @ BBScall. For example: S W3XYZ @ KA3NVP sends a message
to W3XYZ at the KA3NVP bbs. This message will be automatically
forwarded to the KA3NVP BBS for reading by W3XYZ.
Personal Messages. SP Call or SP Call @ BBS
Putting a 'P' after the S in the command makes the message a
personal message to the addressee. Others may not read it.
Otherwise, SP is the same as S.
Traffic. ST Call or ST Call @ BBS
Putting a 'T' after the S command identifies the messsage as
traffic for the NTS system.
Bulletins SB Call of SB Call @ BBS $BulletinID
Putting a 'B' after the S in the command identifies the message
as a Bulletin message.
You may also address a Bulletin to 'ALL' or 'DXERS', etc. It does
not have to be addressed to a station. If the Bulletin is to be widely
diestributed,it should have a Bulletin ID, which is a combination of
letters and numbers that are unique. Usually, amateurs start the bulletin
ID with a part of their call letters followed by a number, as usually
no one will use someone else's call in a Bulletin ID and therefore,
the combination is unique. For Example, W3ABC might use something
like ABC12389. The idea of Bulletin Id's is that bulletins sometimes
spread through divers paths on the network of BBSs . Because each
bulletin has a unique bulletin ID, a BBS may refuse to accept a
bulletin that it already has 'on file'. This eliminates duplication
of effort. Remember, if you send a bulletin to the network, each
bulletin ID must be different and unique to your station. Start
with your call letters followed by 001, say WA3PDQ001, with the
next being WA3PDQ002 and so forth.
NETWORKS
The concept of 'networks' has evolved over the history of packet
mail forwarding. By substituting a 'network name' for the bbs
call letters when sending messages, it is possible to distribute
messages to a number of BBSs. For Example, SB ALL @ PANET would
send a bulletin to everyone on the PANET network. When a BBS
sees such a name in place of the BBS in the Send Command, it looks
in a special file called the 'distribution file', containing the
call letters of all the BBSs in the PANET network. It will attempt
to send a copy of the message to each BBS in the network. This is
where the Bulletin ID becomes important. If the bulletin travels
through the network via two different paths or more, multiple
copies could arrive at some BBSs. The Bulletin ID prevents this
from happening.
