The Fujitsu eval boards use a host-based terminal program to load and
execute programs on the target. This program, pciuh, is relatively
new 
and it replaces the previous ROM monitor, which had the
shell in the ROM.  
To use the GDB remote serial protocol to communicate with a
SPARClite board, link your programs with the
"stub" module `sparc-stub.c'; this module manages the
communication with GDB.  See section `The GDB remote serial protocol' in Debugging with GDB, for more details.
