Subject: [support - Help] Terminal Emulation with IBM / S 390.

Hi All,
I am a student-newbie to RubyForge (and Ruby language & CVS) working on a project
for Terminal Emulation. The dumb terminal interacts with an IBM mainframe through
a ‘multiplexer-MUX’.
The s/w is currently running in ‘C’ on a Windows NT environment and the requirement
is to introduce Object Oriented concepts and C++ was the obvious choice, but
i came across ‘Ruby’ (and also Perl, Python,…etc) after i installed RH8 on
my PC last month. We are actively canvassing the advantages of GNU s/w and philosophy
and would like to simultaneously port it to GNU/Linux platform.
I have read some of the documentation in Ruby.
Before using Ruby as our project language it would be useful to know whether
Ruby has functions, libraries/headers (like C does) capable of handling the
foll. :
1] open and close serial ports,
2] set baud rates,
3] check parity bit/byte,
4] stop bits,
5] Hardware handshaking,
6] selection of port,…
Our existing ‘C’ code is to be ported to the GNU/Linux platform so we are actively
looking at an OOP concept. The part for serial port communication in C++ has
classes so its easier to write customized programs to do most of the above.
Also compatibility with the existing Multiplexer and Cisco Routers is most important
as the company will not make any H/W changes.
We saw that python has some routines for using existing C code so we dont have
to rewrite everything and can make modules containing functions and use it to
operate on files. Does Ruby have any such features. The documentation does not
provide deeper details so it would be nice if anyone could throw some light
on some of the above issues.
Thankyou for your time.
Ciao,
Vidya.

Have a look at this module

If you already have a C module which you want to access via Ruby, then try
http://www.swig.org/

“Ruby/SerialPort is a Ruby’s library that allows you to communicate via
the RS232 port. It supports POSIX (Linux, *BSD, Solaris, AIX), Cygwin
and native Windows.”
It does everything you need and provides a nice OO interface.
We saw that python has some routines for using existing C code so we dont have
to rewrite everything and can make modules containing functions and use it to
operate on files. Does Ruby have any such features. The documentation does not
It does. You can write extensions in C fairly easily (probably easier
than with Python since you don’t have to maintain reference counts).
Moreover SWIG (http://www.swig.org/) is able to generate wrappers for
C/C++ libraries automatically.
