Hmm, in that case why does break_ctl do this:
+ lcr = serial_in(sport, PNX8XXX_LCR);
+ if (break_state == -1)
+ lcr |= PNX8XXX_UART_LCR_TXBREAK;
+ else
+ lcr &= ~PNX8XXX_UART_LCR_TXBREAK;
+ serial_out(sport, PNX8XXX_LCR, lcr);
which appears to imply that the bit for the break state is in the LCR.
Moreover, there isn't a PNX8XXX_INT_* bit defined for break. Confused.
