It is a small hack for bochs that ouputs the serial port data (that on a 
normal PC would go on the wires) to a socket. GDB can than connect to
socket to debug the target. the evironmetn variable BOCHS_GDB_PORT tells
if/and which tcp-port number to use. It is a bit of a hack and i haven't 
realy developed it beter (nor did i write any real docu) , because my
PowerPC hardware was done by that time. And i also found that BOCH's was
in a 
rather abanded state, with the FreeMWare project taking up the
developers energy.
The patch is still on the OAR ftp site , think it is called io_dev or
so, not sure about that.
