Many data lines into Com Port

dion said:

Hi,

I need to accept input from many devices ie thermostat, oxygen level reader etc into a port on my pc. I am not sure which device I should use to accept input, as I might have as many as 20 data streams being accepted at once. This is basically a logging system.

Many thanks.

I will be reading data from digital sensors(approx 10), as well as switching solonoids on and off(approx 12). I want to control all data flow from my pc, and not from a pic just yet. Still working on my electronics knowlege.
