Default Serial communications

Hi, i have recently started using VB so im a total beginner really, but i have a question on serial coms.
I want to interface some sensors to my pc.

Im looking to use either 9 pin or 25 pin connection and have 4 sensors
From a little research i found the following information on the cabling

  Pin Direction Signal
    1 Input DCD Data Carrier Detect
    2 Input RXD Received Data
    3 Output TXD Transmitted Data
    4 Output DTR Data Terminal Ready
    5 Signal Ground
    6 Input DSR Data Set Ready
    7 Output RTS Request To Send
    8 Input CTS Clear To Send
    9 Input RI Ring Indicator

I also found MScomm and was wondering would it be possible to use this to collect data from the Inputs using MScomm. The sensors would not need any outputs to them only to send single changes back to the machine.
For example if i connect the sensors to pins 1, 2, 6, 8, Can i collect the data and when a change occurs increment a counter ?

any information on this would be great thanks
