Adding new target in Targetselection.itb

[msarasa at fh-konstanz dot de]

I've added a new target type succesfully , it's a software-simulated uart, 
that can be called among the remote protocol. It means that now I'm allowed to 
connect a target not only using a real serial line , but with a software 
serial line. Useful to connect software-sim boards.
But , I want to include an option in the dialog-box "target selection" I've 
modified the "targetselection.itb" file and appended a new target 
It looks like:
# Remote
  set gdb_target(remote,pretty-name) "Remote/Serial"
  set gdb_target(remote,defbaud) "9600"
  set gdb_target(remote,baud-rates) {9600 19200 38400 57600 115200}
  set gdb_target(remote,cmd) "remote com1"
  set gdb_target(remote,runlist) {1 1 0 1}
  set gdb_target(remote,after_attaching) {}
  set gdb_target(remotetcp,pretty-name) "Remote/TCP"
  set gdb_target(remotetcp,defbaud) "TCP"
  set gdb_target(remotetcp,baud-rates) {}
  set gdb_target(remotetcp,cmd) "remote tcpX"
  set gdb_target(remotetcp,runlist) {1 1 0 1}
  set gdb_target(remotetcp,after_attaching) {}
  # Simuart E1
  set gdb_target(remote,pretty-name) "Remote/Simuart_e1"
  set gdb_target(remote,defbaud)  ""
  set gdb_target(remote,baud-rates) {}
  set gdb_target(remote,cmd) "remote simuart"
  set gdb_target(remote,runlist) {1 1 0 1}
  set gdb_target(remote,after_attaching) {}


But the problem is that this overwrites the Remote serial option. This way 
just Simuart and TCP are displayed in the option box menu.

What should I modify in order to maintain the other options and add mine 
without overwriting?

Thanks a lot!!
