Thank you for your help!
I know this way "target sim" and have run it
successfully,but I want to try TCP manner on the same
machine(but target and host are different).In this way
I want to use the remote serial protocol,and make
gdbsever run on the simulator.So I change the source
codes of gdb and gdbserver,also I change some contents
of the protocol in order they can run normally.
Regards!
