36 is the card number and starts at
38 for the first attached card.
41 is usually of the form
43 .Pa /dev/cua Oo Pa il Oc Pa D Ar N Pa \&. Ar P
47 .Pa /dev/tty Oo Pa il Oc Pa D Ar N Pa \&. Ar P

58 Disable, enable or query the
60 settings for the given port(s).
62 When ALTPIN is enabled, the CD and DSR lines are logically reversed.
63 This is useful when wiring serial ports to an 8 way RJ45 cable (full
64 10 way RJ45 cables are quite rare).
66 A single ALTPIN setting applies to both of the callout and callin devices.
68 If the driver has been compiled with
70 defined, the following bits from the
72 variable are used to enable diagnostics in the digiboard driver:
73 .Bl -tag -width ".No 1024 ( Em MODEM )"
75 Diagnostics during card attach, detach and initialization.
77 Diagnostics when opening a port.
79 Diagnostics when closing a port.
81 Diagnostics when setting tty device flags.
83 Diagnostics when processing card events.
85 Reports return values from port reads.
87 Reports return values from port writes.
89 Reports receive queue flow control.
91 Reports transmit queue flow control.
93 Diagnostics during interrupts (enable these with care).
95 Diagnostics when setting modem status flags.
97 Reports when a RING is received.
100 Display the card identification string and type ID.
102 Reinitialize the card.
103 For boards with external port modules, it is possible to add or remove
104 modules and dynamically reprobe the number of ports using this switch.
105 All ports on the card must be closed in order to reinitialize the card.
107 It is preferable to reinitialize the card rather than reload the entire
108 digi module as reinitialization only affects the specified board rather
109 than affecting all attached boards.
