Problems with serial card

I have just put my serial card to my replica, and characters it sends have several mistakes
for example, trying "ASCII_hex_Terminal.txt"

As it is:

0750: A2 A0 A9 8D 20 EF FF 8A
0758: 20 EF FF A9 A0 20 EF FF
0760: 8A 20 DC FF E8 A9 A0 20
0768: EF FF 20 EF FF E0 00 F0
0770: 03 4C 54 07 4C 1F FF

As sent:

750: A2 A0 A9 88888 EF FF 8A

0750: A2
0758: 20 EF FF A9 AAAAA EF FF

0758: 20
0760: 8A 20 DC FF E8 A0 20

0760: 8A
0768: EF FF 20 EF FF E00000F0

0768: EF
0770: 03 4C 54 07 4C 1F FFF

what can be the reason? I followed steps to configure hyper terminal as manual says... for several time, with this result
