You possibly could use pin 4 of the link port on the GBC as a serial input. You would need to write a software UART to handle the input data. Since there would be no interrupt involved in monitoring this input pin you would need to devote a good bit of CPU time to monitoring this pin & probably no interrupts would be feasible while looking for serial data. As far as the GB Pocket or GB Classic goes, the standard serial in & out pins on the GB have a serial format that is not compatible with any known serial standard.
