1. A method for performing diagnostic testing in a portable communication device, said method comprising:
sending test signals from a source internal to said device to an output driver of said device, wherein said sending of said
test signals to an output driver comprises transmitting an AT command request to a virtual port of said device via at least
one serial driver, said at least one serial driver then processing said request from said virtual port as though said request
had been received from an external source;
redirecting said test signals back to said portable device; and
processing redirected ones of said test signals within said device as though said test signals had been received at said device
from an external source.
