for example you can (in pc386 bsp):

#include <uart.h>

rtems_task InitTask(rtems_task_argument a)
{
  ...
  i386_stub_glue_init(BSP_UART_COM2);
  set_debug_traps();
  i386_stub_glue_init_breakin();
  breakpoint();
  ...
}

example of starting debuger:
i386-rtemself-gdb -b 38400 -s o-debug/test.exe -x rdbg.com

where rdbg.com can consist of:
...
target remote /dev/ttyS0
breakpoint measure.c:288
continue
...
