Open Modem Firmware ========== Open Modem Firmware is an open source firmware implementation of a AFSK modem supporting 300, 1200 and 2400 baud operation, suitable for communication over a wide variety of analogue mediums, both radio and wired. The firmware is designed for and compatible with [unsigned.io's OpenModem](https://unsigned.io/openmodem/), but can be used on any similar build. Complete modems are available from [the unsigned.io shop](http://unsigned.io/shop), or can be build from scratch by referring to the schematics and documentation on the [OpenModem page](https://unsigned.io/openmodem/) ## A few highlights - 300, 1200 and 2400 baud operation - Full KISS TNC compatibility - Secure in-modem AES-128 encryption - SD card support - Packet logging in PCAP format (WireShark compatible) - Digitally adjustable input and output gain control - Easy to use graphical config utility - Supports standard GPS and bluetooth modules - Supports large packets, 576 byte MTU - Very large in-modem packet queue ## Usage Please refer to the manual and instructions posted at the [OpenModem page](https://unsigned.io/openmodem/). The default serial connection settings are 115200 baud, 8N1. For configuring the modem, please see the OpenModem Config Utility. ## Support OpenModem Development You can help support the continued development of open, free and private communications systems by donating via one of the following channels: - Ethereum: 0x81F7B979fEa6134bA9FD5c701b3501A2e61E897a - Bitcoin: 3CPmacGm34qYvR6XWLVEJmi2aNe3PZqUuq - Ko-Fi: https://ko-fi.com/markqvist
