Visualize incoming/outcoming signal from computer?

Recently, I bought "melabs U2 Programmer with Accessories, http://www.melabs.com/products/usbprog.htm" to program a PIC16F876 chip.

Is there any way to watch each pin of PIC16F875 "incoming or out coming data" on my computer?

I am trying to capture signals on first/second rings of telephone line to decode telephone number, but I am not able see value (series of binary) to decode them. Please help, thanks

Watch pins from what? The computer? The PIC? The USB cable connected to the programmer?

Quite frankly, your post is a bit cryptic.
Single on the 1st/2nd ring from what? The PIC? The phone line? The PC?

I just wonder,

Is there any software or hardware can view each action on specific pin of microcontroller from computer. For example, I programmed PIC16F84A (such as High B0, pause 1000, low B0) then install it in a circuit. So, 10101010 show on computer for each action from this pin.

Sorry, English is my second language.

Hi,
What you are looking for is a logic analyzer. There's a few low-cost ones available that you connect to your PC. LOGIC is a fairly new one that seems extremely easy to use and is quite cheap but there are others.

Thank your for your response.
