Here a decription how to use this features:
Mail via APRS
To send a short mail in the packet-radio-bbs-network you need to address an APRS message to the APRS-Message-Server DB0LJ using the callsign for the bbs DB0LJ-8.The syntax of this services is surely not standard, but my intention was to design it for easy usage with simple portable equipment, no full keyboard, no special characters in 3rd or 4th shift
This message should contain the callsign of the recipient at first position. This field is case-insensitiv.After that you need to enter a delimiter which might be a space or a colon or "-", whatever is conveniant with your equipment.
The rest of the textfield can be used for the message, the limitation is given by the APRS specifications and will be about 67 characters including the address.
Some special characters might not be usuable, please don't use german "umlaute" or other specials which are normally not available in APRS.A small sample entered with UIView32:
To: DB0LJ-8
Port: 1 (please enter appropriate port here, I (=Internet) if you are using TCP/IP on internet or amprnet !)
Text: DL5DI This is a small test via APRS from sunny antarcticaor including the bbs of the recipient:
Text: DL5DI@DB0LJ This is a small test via APRS from sunny antarctica
The message server will acknowledge if successfull or give a short error message in case of any problem.
This answer will only arrive RF users if they are in the range of the path that DB0LJ or the local IGate uses (which is hopefully not TRACE7-7/WIDE7-7 like some people use). As usual the path back to stations is not the same like the incoming.The answer has the following form:
Msg to DL5DI sent ! (DL5DI.43)
or in case of an unknown user:
No User DO1XYZ
The part in brackets behind the positiv message is the message-id, it is created from the call of the sender and the APRS message number that is automatically added invisible from the sender's software. Without this changing part in the answer you would not see it in your software when sending several messages to the same address, because your software would then recognize the answers as dupe messages.
The answer is sent twice, the server does not wait for any ACK and will not reply more often.
It is possible to request a short helpmessage.Sample using UIView32:
To: DB0LJ-8
Port: 1 (please enter appropriate port here, I (=Internet) if you are using TCP/IP on internet or amprnet !)
