APM 2.xx not work with different speed at 57600 in the serial3

[GoogleCodeExporter]

What steps will reproduce the problem?

1.Load APM 2.2x and change in the  

I change the  APM_Config.h file :

#define GCS_PORT 3
#define SERIAL3_BAUD 9600 

2.Set XBee data transfer rate to 9600 (also test with wire and not work)

3- I repeat test with speed at 4800,19200,38400 and 57600 , only work with 
57600.

4 .Do an XCTU range test and monitor bad packets

What is the expected output? What do you see instead?
I expect communications between both XBee modules to be near 100%.  What I find 
is that with APM 2.xx I get that result with a transfer rate of 57600 and not 
work  9600 or 38400.  Upon reloading my APM with 1.xx with the same parameters 
I get 100% transfer rates with all three baud.  Please try and recreate this 
problem.

I'm unable to understand this issue report. I'm flagging it invalid until 
someone can explain it better.

Have you tried 2.12 ? I am able to use 9600 baud with that.

El problema es que al setear a una velocidad diferente a 57600 no logra enlazar.
a 57600 funciona correctamente.
He seteado a 9600 ambos xbee con xctu y funcionan correctamente.
he compilado el apm cambiando el APM_Config.h file :
#define GCS_PORT 3
#define SERIAL3_BAUD 9600 
el soft de telemetria lo configuro a 9600 y no logra enlazarce.

The problem is that on having formed to a different speed from 57600 it does 
not manage to connect.
I have formed to 9600 both xbee with xctu and they work correctly.
I have compiled the apm changing the APM_Config.h file:
#define GCS_PORT 3
#define SERIAL3_BAUD 9600 

The soft of telemetry I it form to 9600 and it does not manage to connect

I am able to use telemetry @9600bps on APM with f/w 2.12, using 2.4GHz X-Bee
