Questions:
1) The Teensy 3.0 has 4 independent RS232 ports, correct?
2) Has the Teensyduino HardwareSerial library been updated to support all 4?
3) Can the Teensyduino 3.0 HardwareSerial library talk to all 4 ports concurrently?
3) Any known issues with the 4x RS232 design and/or library?
4) Can I run an Ethernet shield (eg: http://www.arduino.cc/en/Main/ArduinoEthernetShield) concurrently with the 4 RS232 ports?

Thanks!
 
You might have been confused by the software which appears to offer four serial devices "Serial", "Serial1", "Serial2", "Serial3" but in fact the first one is virtual (USB device) and not a real UART. As t3andy mentions there are only 3 real serial ports. Of course the processor is faster than an Arduino, and it has several timers so software serial is also an option in some cases.
