RTS and DTR should not be modified based on CRTSCTS when calling set_termios. Modem control lines are raised at port open by the tty layer and should stay raised regardless of whether hardware flow control is enabled or not. This is in conformance with the way serial ports work today and many applications depend on this behaviour to be able to talk to hardware implementing hardware flow control (without the applications actually using it). Hardware which expects different behaviour on these lines can always use TIOCMSET/TIOCMBI[SC] after port open to change them.

Currently, users of the Segway RMP200 must use a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a udev rule to get the ftdi_sio module to handle the usb interface and mount it on /dev/ttyXXX. This is not a good solution because some users will have multiple USB to Serial converters which will use the ftdi_sio module.

* USB: ftdi_sio: fix DTR/RTS line modesDaniel Mack2010-06-041-0/+4
| | | | | | | | | | | | | | | | | | | | Call set_mctrl() and clear_mctrl() according to the flow control mode selected. This makes serial communication for FT232 connected devices work when CRTSCTS is not set. This fixes a regression introduced by 4175f3e31 ("tty_port: If we are opened non blocking we still need to raise the carrier"). This patch calls the low-level driver's dtr_rts() function which consequently sets TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in cflags, however, does not reset these bits, and so data is not actually sent out on the serial wire.

* USB: serial: remove multi-urb write from generic driverJohan Hovold2010-05-201-38/+21
| | | | | | | | | | | | | | | | | | | Remove multi-urb write from the generic driver and simplify the prepare_write_buffer prototype: int (*prepare_write_buffer)(struct usb_serial_port *port, void *dest, size_t size); The default implementation simply fills dest with data from port write fifo but drivers can override it if they need to process the outgoing data (e.g. add headers).

Note that this will also make it fairly easy to use the generic fifo-based write implementation: simply unset the multi_urb_write flag and modify prepare_write_buffer (or unset if not using a legacy SIO device). This may be desirable for instance on an embedded system where optimal throughput at high baudrates may not be as important as other factors (e.g. no allocations during runtime and less pressure on host stack).

* USB: ftdi_sio: remove support for 5 and 6 data bitsMark Adamson2010-03-021-3/+1
| | | | | | | | | | Removed CS5 and CS6 from data bits since these are not supported in FTDI hardware. Signed-off-by: Mark J. Adamson <mark.adamson@ftdichip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: ftdi_sio: fix initialisation of latency timeoutJohan Hovold2010-03-021-4/+5
| | | | | | | | | | Latency timeout was read but never stored on port probe. When ASYNC_LOW_LATENCY was cleared the device timeout would get set to 0 rather than the default 16ms. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
