- @@@STARTPACK(ecu;Extended Call Utility)
- <P>
- ECU (Extended Call Utility) is a research and engineering communications
- program originally written for users of SCO UNIX V.3.2/386 and XENIX V
- on 80286 and 80386 systems. Support for other systems has been added
- and further porting is possible with "minor" effort to other systems
- based on or similar to UNIX System V. This preliminary document
- describes ECU functionality and implementation from a technical point of
- view and provides at least rudimentary documentation for its features
- and commands.
- <P>
- ECU provides the classic terminal communications facility of passing
- keyboard data to a serial line (or a telnet TCP/IP connection if
- configured) and incoming data to the computer video display. In
- addition, a dialing directory, a function key mapping feature, and
- session logging are available.
- <P>
- A very flexible procedure (script) language is also incorporated to
- automate many communications tasks. In addition to augmenting
- interactive tasks, by using shell scripts and ECU procedures, ECU can
- perform batch-style communications sessions in an entirely "unattended"
- fashion. Because of limitations of my nroff program, the procedure
- language is described in a separate document.
- <P>
- ECU presents to the host a flexible "ANSI" terminal type, accepting any
- valid video control sequences from MS-DOS or SCO documentation as of
- late 1990. It also fares well, though imperfectly, with Sun and VT-100
- in-band video control sequences. You may disable the ANSI filter if you
- wish. Standards are great: everybody should have one, especially if
- <P>
- they call it "ANSI." For more information, refer to the section below
- titled "ANSI Filter."
- <P>
- The program supports almost any local terminal (console) which can be
- described in a termcap database entry. A robust terminfo or termcap
- description is required for your local console to use ANSI emulation.
- For more information, refer to "Supported Terminals."
- <P>
- ECU supports numerous file transfer protocols: as of this writing,
- XMODEM, XMODEM/CRC, XMODEM-1K, YMODEM/CRC Batch, ZMODEM/CRC-16,
- ZMODEM/CRC-32, and Kermit are supported. For more information, refer to
- the sections describing the individual interactive and procedure file
- transfer commands.
