Are you asking which microcontrollers have two serial ports, or
the serial port supporting chip like level converters with two tx rx
 

The are pics available with multiple UART's use this chip selector link **broken link removed**
 

Hi,

The previous replies refer to chips with inbuilt Usart hardware and this is the more normal approach, however it is not essential for serial communication.

You can use or write you own Software Usart and send / receive data that way through any standard i/o port - its also known a 'bit banging'
You can have more than one software usart running.

If you a communicating between a 5v micro and a PC then you need one of the modern MAX232 type of chips which will produce the required RS232 voltage levels from a single +5v input.
