Problem in interfacing 8051 with weighing machine

[nilesh ghadge]

Actually I am new to this field & want some help from experts out there......
I want to interface 8051 with a weighing machines which works with 4800 & 2400 baud rates. I have no problem with 4800 but as I am trying to read data at 2400 it fails its not giving me any data at all... protocols for both the weighing machines are same
i.e. start character 6 digits end character & '\n'

CPU freq. 11.0592 with 6 clocks/cycle.. & for this freq I am using baud ...

what is the value you are using to get 2400 baud rate????

I am using following values ...

for 9600 //works fine
TH1 = 0xF4;
TL1 = 0xF4;

for 4800 //works fine
TH1 = 0xE8;
TL1 = 0xE8;

for 2400 //not working
TH1 = 0xD0;
TL1 = 0xD0;

here I am using timer 1 in auto-reload mode
