I have been working on a command-line program to control the HomePatrol-1 (Extreme) over the USB serial port.
A public test version of HPe-rc is ready to download at hp.xoynq.com
. It is Windows only at this time. There's no reason it would not work in Linux, but it has not been tested yet.
The entire remote control protocol is implemented. The Audio Feed Mode is probably the most useful feature at this point. The files from the HomePatrol's recording buffer can be downloaded, renamed to a different date format, and put in directories based on the available system information - channel, department, system, service tag or favorites list.
This project started in order to explore using the raw discriminator output. Right now, the program will write the data to a file or another serial port, but it's not in a useful format. (It can be read as raw audio data in a audio processing program.) I am hoping to be able to emulate the RS232 interface described at RS-232 Interface
, but I am at a loss what the data should look like or how to convert the HP's output. Any help or pointers would be great.
Questions, comments and bug reports will also be greatly appreciated.
