what is wrong with this TCP server code?

[palmDev]

can anybody tell me why the following code doesnt
work on PalmOS5? i'm testing it on the simulator.
The same code works fine on the M505 emulator.

I'm using "localhost" as the server and port = "12345"

on the real OS5 device it errors out in the "Listen" api
if it put in a real ip address.

thanks
