What am I doing wrong?

[mankan]

I am trying to test the tx/Rx using PulsIn command. I am sending a pulse by switching high/low a Tx pin and trying to receive the same using PulsIn command.

But at the receiver, I always see a "0" in ID variable, is there something wrong. But when I place a voltmeter at that particular pin, I do observe a high and low pulse but the same in not shown by ID variable.

Any hint, suggestion is appreciated.

Thanks,
Mankan
