you have gained confidence in "normal" packet operation, try setting USERS 2
and get a couple of friends to connect to you. Play with the commands (you can't
hurt the MFJ TNC by issuing commands to it!) and see their effects.
Easy-Mail Mailbox
The Easy-Mail mailbox feature is only valid for the HF and VHF packet mode.
The operation of the Easy-Mail mailbox is quite simple. There is a command in
the MFJ TNC called MAILBOX. Being as the MAILBOX command in your
MFJ TNC is already turned on, makes your Mailbox ready for use, as soon as
your MFJ TNC is powered on. Anyone who operates AX.25 packet can access
your mailbox by establishing a connection to your station by using the standard
packet CONNECT command. Once the connection is made, he can send a
message, obtain a list of the messages in your mailbox, read the messages or kill
any messages addressed to him.
The Easy-Mail mailbox in the MFJ TNC provides approximately 8K bytes of
memory for message storage. However, you can increase the mailbox memory
on your MFJ TNC to 32K, 128K or even an enormous 512K by simply replace
the mailbox RAM chip on the MFJ TNC motherboard. This additional memory
is also battery back-up by the lithium battery on the MFJ TNC mother board.
Addition memory chip can be purchased separately from MFJ Enterprises, Inc.
and it can be easily installed by the user inside the MFJ TNC. Order MFJ-45A
for 32K, MFJ-45B for 128K RAM IC or MFJ-45C for 512K RAM IC. The
number of slots and space available for each memory size are as follows:
Memory Size # of Slots Bytes Avail.
32K 99 32,000
128K 99 per Bank 128,000
512K 99 per Bank 512,000
Set Up your Easy-Mail Mailbox
The MFJ Easy-Mail Mailbox can now be operated independently from the
standard packet operation. There are certain commands which need to be set.
These will be explained later in this instruction.
NOTE: Whenever <CR> is found in this instruction this means to press the
RETURN key, not to type <CR>.
