I do need to find out if omap hardware sets UART_MSR_DCTS when auto CTS
is on. Would you mind running the debug patch below with HW flow control on?

I didn't forget about this. However I told minicom to use hardware flow
control (and I see the driver set the HW bit) but I haven't seen that
uart_handle_cts_change() has been invoked at all. I'm going to check
two other boards and report then.
