I also have:
options         ALT_BREAK_TO_DEBUGGER
I hope it doesn't disturb.

Is that to say rebooting the machine where I want to run gdb?
I've rebooted this machine and nothing happened. 
Is that to say that the target machine ignores the break on the sio?

stty values are:

speed 9600 baud; 0 rows; 0 columns;

cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
        eol2 = <undef>; erase = ^?; erase2 = ^H; intr = ^C; kill = ^U;
        lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q;
        status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W;

I tried to set brkint but after examining it again it is still
cleared.
Is the serial port bogus or is the serial cable an incomplete
implementation?
