Take the ARM E7T for example.

in the serial drive package(e7t)
in function e7t_serial_init( )(which will be called when bootup)  it creat
interrupts for transmit and receive by 1)cyg_drv_interrupt_create(xxx) and
2). cyg_drv_interrupt_attach(xxx),  so will the hal_default_isr( ) in the
hal_interrupt_handlers table entry get overwritten to the ISR of the serial
port which specified in the cyg_drv_interrupt_attach(xxx)? if so how can the
CTRLC be supported? Thanks a lot
