Missing of data in the serial transmission from a PC to RCM4000.

I am transmitting data through serial cable of RCM4000 from a PC. But data missing is taking place frequently. At lower baud rates of 110 ,no data missing takes place. But at higher baud rates missing of data occurs .Why is it so?

Does this happen with our sample programs?

Yes Ma’m.I have send continuous serial data from a PC to RCM4000 and the data is missing at higher baud rates.But when I sent continuous serial data from Hyperterminal ,no data get’s lost.
