I'm working with the MicroModemGP code.

There is only one line I see in device.h that refers to baud rate

// Serial settings
#define BAUD 9600

I changed this , simply, to

// Serial settings
#define BAUD 4800

But the modem data was srambled when I tried to transmit on 4800 baud. It wasn't right until  I transmitted on 9600. So it wasn't changed?

Any ideas?

I thought that changing in the device.h file baud rate from 9600 to 4800 would do the trick. But the modem stays at 9600!?  There must be or other parameters the this newbie is not seeing. Can someone help?

The MicroModemGP is default Serial Direst and wo CSMA. (As I understand it). So there is no need to enable Serial. So Im stuck as to how to enable CSMA still. Any help would be appreciated.

I guess in the  MicroModemGP protocol (which is teh one I will likely use for a serial data application) one would add

void kiss_csma(LLPCtx *ctx, uint8_t *buf, size_t len);

to the LLP.h file ?

Thanks for your help.

Is implemeting CSMA on Simple Serial simply a matter of adding

void kiss_csma(AX25Ctx *ctx, uint8_t *buf, size_t len);

to the SimpleSerial.h file?

I havent been able to find any other locations where CSMA is configured?

Question: Under what conditions would one want to use open-squelch?
