The only change was s/sio/cy/g. -.Pp -Serial ports controlled by the -.Nm -driver can be used for both `callin' and `callout'. -For each port there is a callin device and a callout device. -The minor number of the callout device is 128 higher -than that of the corresponding callin port. -The callin device is general purpose. -Processes opening it normally wait for carrier -and for the callout device to become inactive. -The callout device is used to steal the port from -processes waiting for carrier on the callin device. -Processes opening it do not wait for carrier -and put any processes waiting for carrier on the callin device into -a deeper sleep so that they do not conflict with the callout session. -The callout device is abused for handling programs that are supposed -to work on general ports and need to open the port without waiting -but are too stupid to do so. -.Pp -The -.Nm -driver also supports an initial-state and a lock-state control -device for each of the callin and the callout "data" devices. -The minor number of the initial-state device is 32 higher -than that of the corresponding data device. -The minor number of the lock-state device is 64 higher -than that of the corresponding data device. -The termios settings of a data device are copied -from those of the corresponding initial-state device -on first opens and are not inherited from previous opens. -Use -.Xr stty 1 -in the normal way on the initial-state devices to program -initial termios states suitable for your setup. -.Pp -The lock termios state acts as flags to disable changing -the termios state. -E.g., to lock a flag variable such as -CRTSCTS, use -.Em "stty crtscts" -on the lock-state device. -Speeds and special characters -may be locked by setting the corresponding value in the lock-state -device to any nonzero value. -.Pp -Correct programs talking to correctly wired external devices -work with almost arbitrary initial states and almost no locking, -but other setups may benefit from changing some of the default -initial state and locking the state. -In particular, the initial states for non (POSIX) standard flags -should be set to suit the devices attached and may need to be -locked to prevent buggy programs from changing them. -E.g., CRTSCTS should be locked on for devices that support -RTS/CTS handshaking at all times and off for devices that do not -support it at all. -CLOCAL should be locked on for devices -that do not support carrier. -HUPCL may be locked off if you do not -want to hang up for some reason. -In general, very bad things happen -if something is locked to the wrong state, and things should not -be locked for devices that support more than one setting. -The -CLOCAL flag on callin ports should be locked off for logins -to avoid certain security holes, but this needs to be done by -getty if the callin port is used for anything else. -.Ss Kernel Configuration Options -The -.Em CY_PCI_FASTINTR -option should be used to avoid suboptimal interrupt handling for -PCI Cyclades boards. -The PCI BIOS must be configured with the -.Nm -interrupt not shared with any other active device -for this option to work. -This option is not the default because it is currently harmful in -certain cases where it does not work. -.Sh FILES -.\" XXX more cloning: s/d/c/g and add a ? for the card number. -.Bl -tag -width /dev/ttyic?? -compact -.It Pa /dev/ttyc?? -for callin ports -.It Pa /dev/ttyic?? -.It Pa /dev/ttylc?? -corresponding callin initial-state and lock-state devices -.Pp -.\" XXX more cloning: s/a/c/g.
