    In my project, i have to data transfer between two half duplex transceiver and data received by modem is manipulate by using computer. I am using CC1020 RF Modem.
    Can we directly connect RF modem with computer or i have to put interfacing device like RS232 ?
    According to datasheet we can connect RF modem and pc by using serial port.
    how can i manipulate serial data in my computer program?

    That's absurd !!! You are right!

    ........................

    Are you talking about THIS datasheet?
    The chip has an SPI interface. That means you need to connect it to a microcontroller. The microcontroller could then communicate either via RS232 (need to adapt the voltage levels) or via USB, I guess this requires an USB controller chip.

    thank praondevou
    In this datasheet, we have to built addition i/o matching network and antenna. Is there any wireless modem that is half duplex and single to many connection in low cost?
