[SOLVED] About Xport configurable pins.. Please help :)

The XPort has three pins (CP1-3) that you can configure for General Purpose I/O(GPIO).

Note:
You can also configure the pins for serial port control lines, such as
hardware control, modem control (CTS, RTS, DTR, and DCD), and
diagnostic outputs to LED, using DeviceInstaller.

You can use these GPIO pins to control devices such as relays, servers, lights,
monitor switches, sensors, and even processes such as data transfer.
You can set the functions for the three pins independently and in any combination.
The initial directions (input/output) and active levels (active low or high) at boot up
can also be configured through 77FE, for example, by using DeviceInstaller.
This chapter describes how the directions, active levels, and states can be
dynamically controlled and probed through special port 77F0.

The configurable pins default configuration is:
Function: General Purpose Input
Active Level: Active Low

Every change of state (active/inactive) requires a command over TCP or UDP, and
thus is not very fast. If you use this port for data transfer, the throughput is low,
usually up to 1Kbps.

I tried sending data through CP1 pin but I didn't get it back to PC.
