Unable to read configuration data

Only use 1280000bit/s 8N1 can display uboot,
but some char is wrong,for example,'0x4d' received is '0xed' or '0x8d', I wirte a program to transform it.
if( ch >= 0xe0) {
ch -= 0x80;
}else if(ch >= 0x80 ){
ch -= 0x40;
}
after transform,than display forward right u-boot menu.

but,I also can't input .
when I input char '5' ,it received '4'.

"Unable to read configuration data", means u-boot configfile is wrong, fortunate serial also can conected.
