Hi,
I am using a TS7260's COM2 to connect to another PC to do basic serial
communication. Every time when I receive (RXD) a character from COM2, the
system automatically sends out (TXD) the same character. Why does it do that?
I know that was happeneing because I probed the RXD pin and I saw the exact
waveform from the TXD pin.
When I typed stty -a </dev/ttyAM1, I see the following:
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

as you can see the echo is disabled, how do I disable internal echoing? So I
won't transmit the data when I just received.
Thanks
