sercontrol - serial port controller

About:

It's a kernel module to control the DTR pin of a serial port. The first release was from Gottfried Szing to switch of his computer, at a time when he had no ATX power supply. Now I use it to turn of my HIFI over night (saves a lot of power). Works perfectly!

Now I provide 4 versions: for kernel 2.0.x, 2.2.x, 2.4.0-test1-ac4 to 2.4.0-test2 and 2.4.0-test3. Not tested on linux-2.3.x kernels (till now). Newest versions are working with all 2.4.x kernels.

Usage:

Turn on:

  echo "1" > /proc/sercontrol

  echo "0" > /proc/sercontrol

News:

Just a few updates and compatibility to the newest kernels.

Download:

sercontrol-0.4.tar.gz (version for linux-2.4.x kernels)
sercontrol-0.3.tar.gz (version for linux-2.4.0-test3 kernel)
