Hi,
Please see my software requirement as follows.

I have windows based tool that is communicating with QNX based hardware.

Basic communications are

 1) FTP for file transfer from PC to QNX hardware
 2) Sending some raw data( like configuration data,meter readings etc) from/to PC to QNX based harware
 3) Telnet service ( PC to QNX hardware).

In this scenario, FTP server is running in QNX firmware which listen to port number 21 , Telnet server is listening to 
port number 23 and QNX firmware also had its own server(for Receiving raw data from PC) that is listening to port number
 2000 and QNX system will work as per our expectation.

In this scenario how I can Use inetd service and what is its role ?

Thanks,
Sethu
