This series of patches begins the changes in the serial code to allow more flexible hardware flow control rules. Instead of having fixed models like RTS/CTS or DSR/DTR, the new termiox structure will instead allow to specify which pins will be used. Currently, termiox has four flags: RTSXOFF, CTSXON, DTRXOFF and DSRXON. This is not yet enough to fully specify Linux' CRTSCTS since it uses the DTR always on while the serial port is available (and RTS to signal if the system is ready or not to receive data). The plan is add RTSON and DTRON to termiox to allow the user to specify that those pins will be always set while the serial port is available. These patches are not intended for inclusion, just to continue the discussion. -- Aristeu -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
