Hello,

I have used MAX3232 IC for seial comm with Computer to DSp.

When I Run Sample scia_echoback code, I get absurd characters on the hyperterminal screen.

And what about the software settings - baud rate, etc?

Have you verified the signals with a 'scope?

Shantanu,

Andy is right. Please check whether the baud rate set in the example code matches the baud rate set in the hyper terminal.
