minimodem - general-purpose software audio FSK modem

http://www.whence.com/minimodem/

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, TTY/TDD, NOAA SAME, and Caller-ID.

Transferring data via audio FSK - modem style! - Hackalizer

It’s a software FSK audio modem. It allows you to encode and decode data as audio — just like dialup modems and fax machines used to. This lead me to finding an Arduino project where Emmanuel is creating a long range temperature sensor that transmit’s temperature data over walkie-talkie radios and is decoded by minimodem. On the Arduino ...

The Model G305 FSK Modem is a stand-alone unit that converts RS232 to an FSK Modem. This unit is used with an external radio that has audio Tx and Rx, and supports the use of VHF and UHF “splinter” frequencies. The G305 is typically used at the computer (PC, PLC or RTU) that is polling RTU or RIO units in the field.
