A little problem of my serial port

[yjluo at panjet.net (Yanjun Luo)]

Hi,
My serial port driver can read, write now,but I face another problem.
when I connect one of my serial port(not dbgu) to my PC and running
hyper terminer, I find that only when I press the Enter key then my
board can get what I input before. But if I connect my board to another
serial device, I'll not get Enter key(or "\n"), so how can I get every char
from serial port and don't need Enter key?
