Package sjinn

Simple tool for sending & receiving data from RS-232 devices

S-Jinn is a free, lightweight, open-source Linux application written in
C. It is a simple command-line tool designed for sending & receiving
data from PC controlled TIA/EIA-232 (RS-232) test, measurement,
and control devices.

Depending on your application you may be able to use stty or
C-Kermit, but I believe you will find that S-Jinn is easier-to-use,
more intuitive, and more concise in the area of command-line and/or
scripted RS-232 data acquisition and control.

Popular Linux communications packages like Minicom will also
communicate with RS-232 devices, but they are better suited to modems,
computers, network devices, etc. They typically lack support for any
combination of UART communication settings required by many of the
RS-232 test, measurement, and control devices on the market.

Most communications packages also lack command-line support. Some
provide scripting languages, but S-Jinn frees you from
application-specific languages. S-Jinn simply directs the data to
STDOUT where you can display it, pipe it, and/or redirect it to
be processed by your favorite Unix shell and/or scripting language
regardless of whether you prefer Bash, Python, Perl, Expect, or you
name it.

Other S-Jinn features include the ability to:

    * Control RS-232 DTR and RTS lines from the command-line

    * Display DTR, RTS, CTS & DSR status

    * Send control characters (including the NULL character)

    * Send values in hex

    * Specify read length

    * Set programmable delay times for both send & read.

    * Support for virtually all baud rates, parity, and data lengths
      found in standard PC UARTS

    * Output Formatting: ASCII, hex, ASCII-over-hex, wrap text,
      truncate lines, suppress trailing line feeds
