 minimodem - general-purpose software audio FSK modem
-Copyright (C) 2011-2014 Kamal Mostafa <kamal@whence.com>
+Copyright (C) 2011-2016 Kamal Mostafa <kamal@whence.com>

 Minimodem is a command-line program which decodes (or generates) audio
 modem tones at any specified baud rate, using various framing protocols.
 It acts a general-purpose software FSK modem, and includes support for
-various standard FSK protocols such as Bell103, Bell202, RTTY, NOAA SAME,
-and Caller-ID.
+various standard FSK protocols such as Bell103, Bell202, RTTY, TTY/TDD,
+NOAA SAME, and Caller-ID.

 Minimodem can play and capture audio modem tones in real-time via the
 system audio device, or in batched mode via audio files.

 Minimodem is a command-line program which decodes (or generates) audio
 modem tones at any specified baud rate, using various framing protocols.
 It acts a general-purpose software FSK modem, and includes support for
- various standard FSK protocols such as Bell103, Bell202, RTTY, NOAA SAME,

-Minimodem is a command-line program which generates (or decodes) audio
-modem tones at any specified baud rate, emulating an old Bell-type or
-radio-teletype FSK modem.  The tones can be played to (or recorded from)
-the system audio (PulseAudio or ALSA) or to an audio file.
-
-Minimodem can be used to transfer data between nearby computers using an
-audio cable (or just via sound waves), or between remote computers using
-radio, telephone, or another audio communications medium.

Sebastien Van Cauwenberghe	9a1e8769ab	Add EOT message When program keeps running, the ### EOT message allows the user to know that the stdin has been fully transmitted.	2017-02-16 14:05:31 -08:00

Kamal Mostafa	ea3f837c90	Fix --tx float consistency: disable .wav "PEAK chunk" header Fixes: tests/17-verify-tx-consistent-float.test This might also relate to: https://github.com/kamalmostafa/minimodem/issues/24	2016-04-23 10:34:35 -07:00
Kamal Mostafa	78cff1778b	tests: verify --tx consistency PASS: 16-verify-tx-consistent.test FAIL: 17-verify-tx-consistent-float.test The FAIL is due inconsistency in the .wav header (only for floats) constructed by libsndfile -- its different every wall-clock second. Even just a bare header (no audio samples) shows the effect: minimodem --float-samples --tx 1000 -f /tmp/xx.wav </dev/null sum -r /tmp/xx.wav sleep 1 minimodem --float-samples --tx 1000 -f /tmp/xx.wav </dev/null sum -r /tmp/xx.wav This might also relate to: https://github.com/kamalmostafa/minimodem/issues/24	2016-04-23 10:24:13 -07:00

Chris Osborn	513a11d454	Limit carrier/idle generation for input with delays For non-interactive output (writing to an audio file), generate the idle output carrier for same duration that the input is idle. Makes this case generate an output .wav file of just over 1 second duration: { echo hello; sleep 1; echo world; } \| minimodem --tx -f /tmp/xx.wav 300	2016-04-17 08:49:36 -07:00
Kamal Mostafa	84b2406b97	Rename tv_idletimeout (no functional change)	2016-04-17 08:43:32 -07:00
Kamal Mostafa	ad83ef5df3	Refactor emit idle tone (no functional change) Clean up the "emit idle tone" code, which should never have involved tx_leader_bits_len (that was a copy-paste laziness). "Emit idle tone" simply generates the idle tone for a hardcoded period of time now codified as 'idle_tone_usec' and set to 1/25 of a second (to match the existing behavior).	2016-04-13 09:41:20 -07:00
Colin Ian King	96a60f51b0	initialize ampl_out to avoid it containing garbage static analysis from clang scan-build detected some paths in the call to fsk_frame_analyze where ampl_out is not being set: fsk.c:493:13: warning: Assigned value is garbage or undefined best_a = ampl_out; ..probably the sanest approach here is to initialize it to 0.0 just to avoid it being garbage rather than setting it to zero in the failed error paths in fsk_frame_analyze.

Kamal Mostafa	2b5e2c6a40	Do not enable tx-carrier for non-interactive --file sessions The logic that determined whether to 'block_input' was backwards with respect to non-interactive --file sessions, such that using --file enabled the tx-carrier behavior when it should have disabled it. This went unnoticed because on reasonably fast systems, reading the input data from the file never induce the timeout anyway -- only very slow machines reveal the problem: long gaps of 'mark' between each frame, as if each input character was slowly typed interactively.

Nick Moriarty	8915ce1525	Fix ALSA latency (causing ALSA not to block). With arbitrarily large latency setting (unsigned int)-1, ALSA will happily accept all the samples we want to throw at it. Reducing to a reasonably long (but still sub-second) value of 100ms, we cause ALSA writes to block and work properly with --tx-carrier.	2015-04-22 17:48:28 +01:00
Nick Moriarty	ecebf013f0	Add ability to output a carrier while waiting for data Added --tx-carrier, which continues to output a tone while a blocking source waits for more data on stdin.	2015-04-22 17:48:28 +01:00
