Using Email client - Outlook Express
You can use Outlook Express for the email client to create
outgoing ARQ traffic. Just remember that
you should create all email traffic as ASCII text and not HTML text to
reduce the size of the message body. You are going to send this
via an RF link and not over the internet with a high speed connection.
Create your email just as you would for transfer over the internet and then save it in the Drafts
folder. In Outlook Express, click Create Email
and use the format, name@phonenumber, such as information @8005551212,
for the address if it is to be delivered by phone, and is not an email.
Save each message in the Drafts folder by clicking File
, and then Save
Exit the composition window. Open the ARQout folder
(located at c:\NBEMS\Mail\ARQout)
on the desktop along with Outlook Express as shown below. Then
drag the message from the "To ... Subject" area of Outlook Express and
drop it on the ARQout folder. This places them in a folder that
flarq can locate.
When you select the flarq menu item "Send / Email" a dialog will open
that shows the contents of the messages that are in the ARQout folder:
Multiple email entries would appear on separate lines with scroll bars
as appropriate. You highlight the desired file and then press
"Send" or the Enter key to commence the file transfer. The email
may contain attachments (which may be images) or be just plain
text. Remember that this is a fairly slow transfer process so
small is beautiful. If the email has images then it will be in
html and base-64 format. That adds a lot of overhead to the
email. "Cancel" aborts the email transfer
process. After a successful transfer from sending to receiving
station the email is automatically moved from the ARQout to the ARQsent
folder. If you are using Outlook Express you can open the
c:\NBEMS\Mail\ARQsent folder the same way that the ARQout folder can be
opened. At the
receiving end the email will be placed in the Sylpheed ARQin
folder. Sylpheed does not need to be executing for this to occur
at either end.
Using Email client - Sylpheed
flarq has been optimally designed to interoperate with Sylpheed as
its email client for emergency communications of email traffic.
When you install Sylpheed you will be asked to choose a default
directory for the mail store. On Linux this should be the default
$HOME/Mail. On Windows you should choose c:\NBEMS\Mail.
additonal folders are used for transferring files between the flarq
application and Sylpheed. These are:
- ARQout, and
You can create these folders from within the Sylpheed application.
Sylpheed on Windows - idential on Linux
The above image shows the folders already in place. If they were
not present they could be created by right clicking on the "Mailbox
(MH)" icon and selecting "Create new folder". Name each new
folder as specified above and shown in the image. These folders
are required for flarq to be able to work with the Sylpheed email
messages. Each message in Sylpheed is a separate file.
These are usually numbered sequentially in each of the Sylpheed
folders. flarq manages the correct sequential naming of files
as they are transferred in, out and moved between these three folders.
If you run the flarq application before Sylpheed then the
c:\NBEMS\Mail and the c:\NBEMS\Mail\ARQin, ARQout, and ARQsent folders
will be created by that appliction and will appear in the Sylpheed
To create a new email traffic you press the "Compose" button.
Fill out the email as usual and then press the "Draft" button from
within the composer. The new message for transfer via flarq is
now in the Drafts folder shown above. Open that folder by
clicking on it. Select the desired draft message and drag and
drop in onto the ARQout folder icon. That's it! The message
is now ready for flarq to perform the ARQ transfer.
Upon completion of the transfer flarq will move the message to the
ARQsent folder. Sylpheed will not immediately recognize that the
change has occured. That is easily accomplished by either
changing to another folder and then back again or by right clicking on
the ARQout (or ARQin, or ARQsent) folder icon and selecting "Update
summary". Sylpheed will re-read the folder contents and adjust
it's views accordingly.
Incoming traffic will be placed in the ARQin folder. You may have to refresh the folder as described above.
flarq can find and parse the newly created email document that has
been moved or copied to the ARQout folder. If you select to send email
a picker dialog will appear that lists all
of the out going email traffic that is contained in the Sylpheed ARQout
Other Email clients
If you use an email client other than Sylpheed or Outlook Express you
can transfer emails as above. Just be sure that the emails have
file names with the extension "eml" as in "mytest_message.eml".
Aborting a transmission
The transmission may be aborted by either the sending or the receiving
station at any time during the file transfer. When Connected
and transferring a file, the Connect button is re-labeled Abort
Since data is sent in multiple
blocks the actual abort will take place at the conclusion of the
current group transmission. Abort will cause the transfer to be
interrupted. The connection will be maintained and a new transfer can be initiated if required.
After a connection is established the two stations can
exchange text using the "Plain Talk" entry control at the bottom of
the main dialog. Enter up to 80 characters and then press the Enter
key to transmit the text. This text is sent UNPROTO, which means
that NO repeat request will be made. The block is sent without
any acknowledgement from the receiving station. This is not an
ACK/NACK system, but meant only as a way of allowing quick operator to
operator exchanges without having to disconnect and use the digital
modem program keyboard entry. "Plain Talk"can be interspersed with
normal ARQ file transfer blocks.
