- COMPOSE BINARY
-
- Envoy 100 supports the transfer of binary (8 bit) files using the XMODEM
- file transfer protocol. Both CRC and CHKSUM versions of XMODEM are
- supported.
-
- If COMPOSE BINARY is entered at the Command? prompt the user is required to
- enter the TO, CC, BCC and Subject fields as well as text (if any) in the
- same manner as the COMPOSE script. However after entering '[.cr]' to end
- the text input the user is then prompted for:
-
- File Name: (up to 20 characters) and
- File Format: (up to 20 characters).
-
- These fields are labels which can be used to identify the binary file that
- follows. They can be left blank by entering [cr].
-
- After entering the 'File Format:' the user is prompted to 'Initiate
- Transfer' (send BREAK to cancel). At this point the user must invoke the
- XMODEM file transfer from their computer to send a binary file to Envoy
- 100. The exact manner in which XMODEM is invoked depends on the
- communication software being used and the documentation for that package
- should be consulted for this information.
-
- After the file is transferred the user will receive a summary status line
- from Envoy and can then send, edit or save the message in the same manner
- as currently allowed. The restrictions on editing binary attachments are:
-
- 1) A binary attachment is stored as a single line in the workspace.
-
- 2) The binary attachment itself cannot be modified.
-
- 3) The File Name: and File Format: text can be edited like any other text.
- However any attempts to edit the labels themselves will result in the
- edit command being cancelled.
-
- 4) The line(s) containing the binary attachment can be copied, deleted and
- moved in the same manner as a text line(s).
-
- If the XMODEM transfer fails or is cancelled for any reason, the user is
- informed with a system message and is returned to the Command? prompt. The
- message with the (incomplete) binary attachment will not be posted.
-
- The XMODEM transfer can be cancelled by issuing a BREAK from the
- communication software package. Please consult the documentation for your
- communication software for the details on cancelling an XMODEM file
- transfer.
