I'm looking at the ATMega328p data sheetATMega328p data sheet, and an Arduino Pin diagram, trying to determine if the chip can support three UART connections... I see that PD0 and PD1 are "USART" In and Out... So does that mean the other 10 or so Digital pins can be used for "UART" communications?

I have a need to connect three UART devices through the ATMega chip. The ATMega will forward traffic between two of the devices at a time, depending on which mode it's in.

Thanks Brad
