==Firmware File Format==
There are two primary types of entries in the .hex file format: data lines and comments.

* Data lines start with a colon (:) and are comprised of binary data in hexadecimal format.
* Comments begin with a semi-colon. (;) These should be ignored by the software doing the firmware upload.

==Bootloader==
===Getting into the Bootloader===
During the boot process the AlarmDecoder will present a <tt>!boot</tt> message. If an '=' is sent to the device before the boot process is finished it is halted and the device drops into firmware upload mode where you will be presented with a <tt>!load</tt> prompt. If a previous firmware upload failed you will automatically be dropped into the boot loader.

===Uploading Firmware===
After the <tt>!load</tt> prompt is received you may begin uploading firmware. This is done by sending the data lines from the firmware file, including the colon, to the device followed by a single carriage return.

There are a few responses you should expect from each line that's sent:
* <tt>!0000:0000</tt>, <tt>!00FF:0000</tt>, and <tt>!ae</tt> - These are positive responses.
* <tt>!no</tt> - Improperly formatted input. Make sure the colon is present.
* <tt>!ce</tt> - Checksum error.
* <tt>!ol</tt> - Invalid memory location.
* <tt>!ok</tt> - The firmware upload completed successfully.
