The ATtiny85 doesn't have a hardware serial port, so this makes sense.

ATTinyCore provides a Serial object that does software serial, so you might like that one:

Otherwise, it will be helpful if you provide more information about what you're doing. How do you expect to get the serial communication?

Which Arduino core for tiny 85 are you using? I would recommend

https://github.com/SpenceKonde/ATTinyCore

Edit: @pert beat me to it.

I'm making an ac dimmer base on ir remote control using triac and optocoupler and 3 relays i want to use serial for ir remote

If ir value match with serial monito value than turn on relay or diming the light
