what is DTR?

Atleast in my case, i use it for powering on the amplifier AFTER windows is ready.. It also turns my amplifier off before windows shuts down completely.. This way, i can avoid the start-up beep from my speakers.. Oh yeah, I also avoid the "bump"-sound from my speakers at shutdown..

It can ofcourse be used for something else than an amplifier.. DTR is the name of serial port pin no. 4 (Data Terminal Ready) .. You should find schematics on the web, if not - get back to me and i'll post one..

Good Luck!
