Operating Systems Linux programming advice needed.... Post 47347 by trostycp on Sunday 8th of February 2004 08:51:44 PM

Question programming advice needed....

i'm a grad student taking a UNIX course and a networks course (i have a background in C++ and JAVA). i'm trying to combine the two classes.
My questions stems from a networks programming homework assignment below:
"Using the operating system and language of your choice, develop a program to set and monitor a serial interface. Display the interface status at the start of the program. Initialize the interface (DTR, RTS, 8 data bits, no parity, 19,200 bps). Report all interface status changes."

first question:
I want to try this on Linux RedHat (newbie)....can this program be done using shell commands (bash or korn)? Or are those too 'low-level' and i should write it in JAVA on the linux machine?

second question:
once i do start the programming (regardless of language)....if i compile and run it on the RedHat linux machine any idea whether i can connect serial ports (RJ-11 connection) to a computer running Windows XP Pro and not have any interference with the different OSs?

Net::CLI::Interact::Transport::Serial(3pm)		User Contributed Perl Documentation		Net::CLI::Interact::Transport::Serial(3pm)

NAME
Net::CLI::Interact::Transport::Serial - Serial-line based CLI connection VERSION
version 1.121640 DECRIPTION
This module provides a wrapped instance of a Serial-line client for use by Net::CLI::Interact. INTERFACE
app On Windows platforms you must download the "plink.exe" program, and pass its location to the library in this parameter. On other platforms, this defaults to "cu", which again you must download and install. runtime_options Based on the "connect_options" hash provided to Net::CLI::Interact on construction, selects and formats parameters to provide to "app" on the command line. Supported attributes: FIXME: on Windows platforms, only the device attribute is supported. device (required) Name of the device providing access to the Serial-line (e.g. "/dev/ttyUSB0" or "COM5". parity You have a choice of "even", "odd" or "none" for the parity used in serial communication. The default is "none". nostop You can control whether to use "XON/XOFF" handling for the serial communication. The default is to disable this, so to enable it pass any True value. speed You can set the speed (or baud rate) of the serial line by passing a value to this named parameter. The default is 9600. reap Only used on Unix platforms, this installs a signal handler which attempts to reap the "ssh" child process. Pass a true value to enable this feature only if you notice zombie processes are being left behind after use. COMPOSITION
