does anybody know how to make an IR frequency reader by com port?
or a 7-segment?

What exactly do you want to measure?

- the frequency of the Infra Red light beam?
- the frequency of the signal's symbols (Baud)?
- the frequency of the carrier wave (in case it is not baseband transmission)?

Get a frequency to voltage converter chip, like the LM2917
