Unknown programs in Startup: Bluetooth, Digital Line Detect

[FredFromNYC]

My ThinkPad came with two programs in the Startup group that I cannot identify. One is "Bluetooth", the other "Digital Line Detect". The shortcuts point to the following programs.

C:\Program Files\ThinkPad\Bluetooth Software\BTTray.exe
C:\Program Files\Digital Line Detect\DLG.exe

What is the purpose of these applications and can I remove them from the Startup group? I don't use Bluetooth and disabled it in ThinkPad Configuration.

You can remove Bluetooth from the startup if you don't want it.

Also, the digital line detector is useful if you use your modem alot; it does, suprise, as its name indicates and detects the characteristics of a digital modem line.

They don't need to be in startup if you don't use the services.

Thanks for the information. I will remove both items as I use neither Bluetooth nor the modem.
