Serial stuff

On the AximX50 wiki page
(http://www.handhelds.org/moin/moin.cgi/DellAximX50) there seems to be a
contradiction in the signal level specifications:

  "X50V uses TTL serial interface (3.3 v)"
  "25 - 5V TTL output ?"

Is the serial signal level 3.3V or 5V?

Secondly, would this level converter
(http://www.piclist.com/techref/io/serial/RCL1.htm) work using the USB
client +5V (pin 21)?
