Port B for RS232

Hello,

I am using RCM3100.
I am able to send characters from Rabbit and view them on Hyperterminal.
But I am not able to receive the characters sent from PC to Rabbit.

The code I am using given below.

#define BINBUFSIZE 15

#define BOUTBUFSIZE 15

#ifndef _232BAUD

#define _232BAUD 115200

#endif

serBopen(_232BAUD);

serBwrFlush();

serBrdFlush();

for(;;)

{

costate {

for (;;)

{

// serBputc (cOut); // Send lowercase byte

while ((nIn1=serBgetc()) == -1); // Wait for echo

serBputc (toupper(nIn1)); // Send the converted upper case byte

// while ((nIn2=serCgetc()) == -1); // Wait for echo

printf ("Serial B sent %c\n",toupper(nIn1));

waitfor (IntervalMs(500));

}

}

Can any one help me in setting up the rabbit to receive characters sent from
other device on Serial port B?

Thanks Start a New Thread

Do you have hyperterminal set for no handshaking?

I have found Hyperterm a bit cranky in the past. One thing that has
helped me in the past is to turn off the flow control in the
hyperterm settings.

Hope that helps

So you know that the PC can receive characters, and that the Rabbit can
send them. That's a good start.

Try connecting the Rabbit Tx and Rx lines: this will verify that the
Rabbit can also receive data.

Then try connecting the PC Tx and Rx lines: this will verify that the
PC can also send data.

If you have standard 9-pin D connectors, it's really easy to use a
staple or paper clip to short pins 2 and 3. :)

Thank you. I have changed the hyperterminal flow control to "None" and it is
working fine.

Thanks

Do you have hyperterminal set for no handshaking?
