FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

digictl - control Digiboard devices

 

NAME

      digictl - control Digiboard devices
 

SYNOPSIS

      digictl -a disable | enable | query device ...
      digictl [-d debug] [-ir] ctrl-device ...
 

DESCRIPTION

      The digictl utility provides control of the Digiboard installed with the
      given ctrl-device name and provides control of individual digiboard
      devices.  A digiboard ctrl-device is usually of the form /dev/digiN.ctl
      where N is the card number and starts at “0” for the first attached card.
      A digiboard device is usually of the form /dev/cua[il]DN.P or
      /dev/tty[il]DN.P where N is the card number and P is the port number.
 
      The following flags are recognized:
 
      -a disable | enable | query
                  Disable, enable or query the ALTPIN settings for the given
                  port(s).
 
                  When ALTPIN is enabled, the CD and DSR lines are logically
                  reversed.  This is useful when wiring serial ports to an 8
                  way RJ45 cable (full 10 way RJ45 cables are quite rare).
 
                  A single ALTPIN setting applies to both of the callout and
                  callin devices.
 
      -d debug    If the driver has been compiled with DEBUG defined, the fol‐
                  lowing bits from the debug variable are used to enable diag‐
                  nostics in the digiboard driver:
 
                  1 (INIT)      Diagnostics during card attach, detach and ini‐
                                tialization.
 
                  2 (OPEN)      Diagnostics when opening a port.
 
                  4 (CLOSE)     Diagnostics when closing a port.
 
                  8 (SET)       Diagnostics when setting tty device flags.
 
                  16 (INT)      Diagnostics when processing card events.
 
                  32 (READ)     Reports return values from port reads.
 
                  64 (WRITE)    Reports return values from port writes.
 
                  128 (RX)      Reports receive queue flow control.
 
                  256 (TX)      Reports transmit queue flow control.
 
                  512 (IRQ)     Diagnostics during interrupts (enable these
                                with care).
 
                  1024 (MODEM)  Diagnostics when setting modem status flags.
 
                  2048 (RI)     Reports when a RING is received.
 
      -i          Display the card identification string and type ID.
 
      -r          Reinitialize the card.  For boards with external port mod‐
                  ules, it is possible to add or remove modules and dynamically
                  reprobe the number of ports using this switch.  All ports on
                  the card must be closed in order to reinitialize the card.
 
                  It is preferable to reinitialize the card rather than reload
                  the entire digi module as reinitialization only affects the
                  specified board rather than affecting all attached boards.
 

HISTORY

      The digictl utility first appeared in FreeBSD 5.0.
 

BUGS

      It should be possible to reinitialize a board without closing all of the
      existing ports.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
