COMPOSING
MESSAGES
OFFLINE
When the 5100 is offline, you can compose messages, write them on tape for later
transmission, or print them. Writing and printing start with the data moved to the
input line and continue to the end of the extended display.
To compose a message in the extended display with the 5100 offline, follow these
steps:
1. Press the edit key (CMD and alphameric 2) to start the edit operation.
2. Enter a line from the keyboard.
3. Press the home key (CMD and alphameric 8). This enters the line in the
extended display and moves the data on the display screen up one line.
Repeat steps 1, 2, and 3 until the message is complete. The data in the extended
display can now be written on tape or printed.
To write the data on tape, use the following procedure:
1. Insert the tape cartridge in the tape unit and open the file for output with
the
~OPEN
command.
2. Move the line with the
~OPEN
command back to the input line, then press
the edit key.
3. Press the line delete key (CMD and alphameric: 3). This deletes the
~OPEN
command from the extended display so it will not be written on tape.
4. Press the home key and move the first line of the message you want to
write on tape to the input line.
5. Press the edit key (CMD and alphameric 2) and then press the write key
(CMD and alphameric 9) to write the data on tape.
6. Enter the
~CLOSE
command before removing the cartridge to ensure that
the data is stored.
To print the data in the extended display, move the first line of the message to be
printed to the input line, start the edit operation by pressing the edit key, and press
the print key (CMD and alphameric 7). This procedure can be repeated to obtain
multiple copies.
TRANSMIT INTERRUPT
When the 5100 is transmitting, the remote system can interrupt the transmission,
cause the 5100 to go to receive status, and transmit a message. During option P,
this interrupt is honored and the message is accepted. During option T, the
interrupt is honored only during sign-on or if no tape or printer operation is in
progress.
