Free modem software for linux

kmodemlights is a applet for the KDE-panel kicker, that watches a modem and allows to connect and disconnect the modem. It is "inspired" by modemlights (read: its a clone).
Main features:
- the connection-state on the button (offline - awaiting connection - online)
- two LEDs showing activity for Rx and Tx, much like a modems lights (hence the name). The update-frequency is configurable from 2 to 5 (default is 5).
- a graph displaying Rx-volume and Tx-volume (updated every 2 seconds).
- The bytes received per second (updated every second), as numerical value.
- The time since the modem is online.
The colors of the lights, button-icons (await- and online- state) and the graph is configurable, and the icon that shows the state of connection comes in three sizes.
kmodemlights still has problems operating in a vertical panel!
Enhancements:
- configurable shortcut to go on- or offline

Modem::Vgetty is a Perl interface to vgetty(8).

SYNOPSIS

use Modem::Vgetty;
$v = new Modem::Vgetty;

$string = $v->receive;
$v->send($string);
$string = $v->expect($str1, $str2, ...);
$v->waitfor($string);
$rv = $v->chat($expect1, $send1, $expect2, $send2, ...);

$ttyname = $v->getty;
$rv = $v->device($dev_type);
$rv = $v->autostop($bool);
$rv = $v->modem_type; # !!! see the docs below.

$rv = $v->beep($freq, $len);
$rv = $v->dial($number);
$rv = $v->play($filename);
$rv = $v->record($filename);
$rv = $v->wait($seconds);
$rv = $v->play_and_wait($filename);
$v->stop;

$v->add_handler($event, $handler_name, $handler);
$v->del_handler($event, $handler_name);
$v->enable_events;
$v->disable_events;

$number = $v->readnum($message, $tmout, $repeat);

$v->shutdown;

Modem::Vgetty is an encapsulation object for writing applications for voice modems using the vgetty(8) or vm(8) package. The answering machines and sofisticated voice applications can be written using this module.

Cable Modem Counter is a cable modem (or any Ethernet connection) IP byte logger. It is not a packet sniffer, it just gathers network statistics.

It is composed of two parts:

A daemon, which logs all the incoming/outgoing connections and creates pairs of source/destination IP addresses with a byte counter and direction of traffic (inbound or outbound) attached. It stores it periodically on a file (or files).It also accepts network connections to gather the statistics and can also run users scripts which can send commands to the daemon and receive information.
An user application, which can be run on console or X (wmaker/kde bar?) and connects to the daemon and collects the statistics, and then making the separation between national/international , inbound/outbound , etc (not done yet)

dterm application is a simple terminal emulator, which doesnt actually emulate any particular terminal. Mainly, it is designed for use with xterm and friends, which already do a perfectly good emulation, and therefore dont need any special help; dterm simply provides a means by which keystrokes are forwarded to the serial line, and data forwarded from the serial line appears on the terminal.

Running dterm

dterm is invoked thusly:
dterm [options|device ...]

dterm attempts to read the file ~/.dtermrc for options; if this doesnt exist, it tries /etc/dtermrc. Then it parses the options passed on the command line.

The options read should include a device name, e.g "ttyS0" or "ttyd0" for the first serial port on a Linux or FreeBSD system respectively.

Once started, dterm can be got into command mode using Ctrl/]. Press enter once from command mode to get back into conversational mode. (The command character can be changed with the esc= option, e.g. esc=p to use Ctrl/P instead of Ctrl/].)

Options:

The following options can be used from command mode

300, 1200, 9600 etc: Set speed, default 9600.
5, 6, 7, 8: Set bits per character, default 8.
1, 2: Set number of stop bits, default 1.
e, o, n, m, s: Set parity to even, odd, none, mark or space, default none.
cts, nocts: Enable / disable CTS flow control, default nocts.
xon, noxon: Enable / disable XON/XOFF flow control, default noxon.
modem: Enable / disable modem control (hang up modem on exit, exit if modem hangs up), default nomodem.
bs, nobs: Enable / disable mapping of Delete to Backspace, default nobs.
del, nodel: Enable / disable mapping of Backspace to Delete, default nodel.
maplf, nomaplf: Enable / disable mapping of LF to CR, default nomaplf.
igncr, noigncr: Ignore / output carriage returns, default noigncr.
crlf, nocrlf: Enable / disable sending LF after each CR, default nocrlf.
b: Send a 500 ms break.
dtr, nodtr: Raise / lower DTR, default dtr.
rts, norts: Raise / lower RTS, default rts.
d, r: Toggle DTR / RTS.
esc= : Set command mode character to Ctrl/ (default ])
@ : Read and process configuration from .
! : Execute shell command
show: Display current configuration and modem status.
help, h, ?: Display a summary of commands.
version: Display version, copyright and warranty information.
quit, q: Exit

Examples:

Connect via ttyS1 to a system running at 2400 bps, 7 bits even parity:

dterm ttyS1 2400 7 e

Send a break in a running session:

^]
dterm> b
dterm>

MobileRemoteSE is a light (non-Java), serial-over-bluetooth-based remote control for Amarok.
Uses the Sony Ericsson AT command set, and supports the following Sony Ericsson phone models: K750, W800, Z520, W550, W600, W900, W810, Z530, W300, K510, K310, W700, Z525, W710, Z550, Z558, K320
Main features:
- Appears under "Entertainment" menu on the phone.
- Supports Play/Pause, Next, Prev, Stop, Volume Up/Down operations from mobile phone.
- Displays the current running track on Amarok in the phone menu title.
- Since J2ME is not used (unlike some other alternatives), the remote control can be used while running some other application on non-multitasking models.
Instructions:
1) Bind /dev/rfcomm0 to the serial-over-bluetooth channel of your mobile. Please refer to your distro docs or howtos on the internet to find out how to do this.
2) Install Device::Modem package for Perl. You can either use your distro packages for this, or install through CPAN as:
cpan -i Device::Modem
3) Install and start script from Amarok.

Data::ENAML is a Perl extension for ENAML data representation.

SYNOPSIS

use Data::ENAML qw (serialize deserialize);

print serialize(login => {nick => Schop,
email => ariel@atheist.org.il,
tagline => If I had no modem I would not lose Regina});

$struct = deserialize(bad-nick: {nick: "c00l dewd" text: "spaces not allowed"});

ENAML stands for ENAML is Not A Markup Language. (And as we all know, Gnu is Not UNIX, Pine Is Not Email, Wine Is Not Emulator, Lame Aint Mp3 Encoder and so on).

ENAML was defined by Robey Pointer for use in Say2, check http://www.lag.net/say2.

udpeq is a program that balances UDP traffic over parallel routes. This is useful if you want to connect two endpoints through several slow or unreliable channels. For example, if you have 3 modem lines and a one-way satellite link, you might want to bond all of these together to form a faster, more reliable "virtual" connection.

udpeq by itself just shuttles UDP packets between two endpoints. You will almost certainly want to use a higher-level tunnel on top of udpeq to provide a "real" IP connection. CIPE or OPENVPN are perfect for this job.

Existing solutions of this nature (for example, multi-link ppp) tend to make simplistic assumptions about the bandwidth and availability of the channels. udpeq attempts to dynamically adjust to changing conditions, being as robust as possible while still being able to maximize throughput.
