Serial functions don't work with attiny85 board library

So I tried to verify/comple a serial communication test with the attiny85 board settings and I managed to get some errors with some undeclared Serial functions.

Is it possible that the attiny85 is not compatible with that function and if isn't is there anyway to still use that communication with something else?

thanks for your time.

ATtiny85 doesn't have any hardware serial port, so you will have to use the SoftwareSerial library :wink:

ok Thanks.
