[ECOS] At input of a symbol $ restart redboot

[Igor Ivanov]

Hello

At input of a symbol $ restart redboot.

I add debugging messages in 
ecos-trunk-full-060604\ecos\packages\redboot\current\src\main.c(383)
============
#ifdef CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
            if (res == _GETS_GDB) {
  int dbgchan;
                hal_virtual_comm_table_t *__chan;
                int i;
                // Special case of '$' - need to start GDB protocol
                gdb_active = true;
                // Mask interrupts on all channels
diag_printf("CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS = 
%d\n",CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS);
diag_printf("Mask interrupts on all channels:\n");
                for (i = 0;  i < CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS; 
i++) {
//
diag_printf("- channel %d\n",i);
//
                   CYGACC_CALL_IF_SET_CONSOLE_COMM(i);
                    __chan = CYGACC_CALL_IF_CONSOLE_PROCS();
                    CYGACC_COMM_IF_CONTROL( *__chan, 
__COMMCTL_IRQ_DISABLE );
                }

At input of a symbol $ I receive:

The '$' character is used to break into GDB - RedBoot is doing the right
thing, it's just silent about it.

If you need to type a '$' to RedBoot, precede it with \, e.g. \$
