The dgb driver is redundant with the digi driver in the tree. It uses

lots of old interfaces, and digi now supports all cards that dgb
supported.  The author of the driver says that this is no longer
necessary.

-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for DigiBoard PC/Xe and PC/Xi series intelligent
-serial multiport cards with asynchronous interfaces based on the
-.Tn EIA
-.Tn RS-232C
-.Pf ( Tn CCITT
-.Tn V.24 )
-standard.
-.Pp
-Input and output for each line may set to one of following baud rates;
-50, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, 9600,
-19200, 38400, 57600, or for newer versions of cards 115200.
-.Pp
-The driver doesn't use any interrupts, it is
-.Dq polling\-based .
-This means that
-it uses clock interrupts instead of interrupts generated by DigiBoard cards and
-checks the state of cards 25 times per second.
-This is practical because the
-DigiBoard cards have large input and output buffers (more than 1Kbyte per
-port) and hardware that allows efficiently finding the port that needs
-attention.
-The only problem seen with this policy is slower
-SLIP and PPP response.
-.Pp
-Each line in the kernel configuration file describes one card, not one port
-as in the
-.Xr sio 4
-driver.
-.Pp
-The
-.Cm flags
-keyword may be used on each
-.Dq Li "device dgb"
-line in the kernel configuration file
-to change the pinout of the interface or to use new PC/Xe cards
-which can work with an 8K memory window in compatibility mode
-(with a 64K memory window).
-Note
-that using 8K memory window doesn't mean shorter input/output buffers, it means
-only that all buffers will be mapped to the same memory address and switched as
-needed.
-.Pp
-The
-.Cm port
-value must be the same
-as the
-port
-set on the card by jumpers.
-For PC/Xi cards the same rule is applicable to the
-.Cm iomem
-value.
-It must be the same as the memory address set on the card
-by jumpers.
-.\"Some documentation gives the address as a ``paragraph'' or ``segment'';
-.\"you can get the value of address by adding the digit "0" at end of
-.\"paragraph value, e.g., 0xfc000 -> 0xfc0000.
-For PC/Xe cards there is no need to use jumpers for this purpose.
-In fact there are no jumpers to do it.
-Just
-write the address you want as the
-.Cm iomem
-value in kernel config file and the card will be programmed
-to use this address.
-.Pp
-The same range of memory addresses may be used
-for all the DigiBoards installed
-(but not for any other card or real memory).
-DigiBoards
-with a large amount of memory (256K or 512K and perhaps
-even 128K) must be mapped
-to memory addresses outside of the first megabyte.
-If the computer
-has more than 15 megabytes of memory then there is no free address space
-outside of the first megabyte where such DigiBoards can be mapped.
-In this case you
-may need to reduce the amount of memory in the computer.
-But many machines provide a better solution.
-They have the ability to
-.Dq "turn off"
-the memory in the 16th megabyte (addresses 0xF00000 - 0xFFFFFF)
-using the
-BIOS setup.
-Then the DigiBoard's address space can be set to this
-.Dq hole .
-.\" XXX the following should be true for all serial drivers and
-.\" should not be repeated in the man pages for all serial drivers.
-.\" It was copied from sio.4.  The only changes were s/sio/dgb/g.
-.Pp
-Serial ports controlled by the
-.Nm
-driver can be used for both
-.Dq callin
-and
-.Dq 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
-.Dq 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
-.Dv CRTSCTS ,
-use
-.Dq Li "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
-.\" XXX change next line in other man pages too, and rewrite this paragraph.
-work with almost arbitrary initial states and 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.,
-.Dv CRTSCTS
-should be locked on for devices that support
-RTS/CTS handshaking at all times and off for devices that don't
-support it at all.
-.Dv CLOCAL
-should be locked on for devices
-that don't support carrier.
-.Dv HUPCL
-may be locked off if you don't
-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
-.Dv 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.
