For large systems an external terminal server may provide a nearly arbitrary number
of serial ports. The terminal server is connected to the VLC via Ethernet.
The serial IO cards are not automatically recognized by the VLC. Each card must be configured to the
address/irq settings expected by the software. Then the software must be told which cards are installed.
The card configuration is defined in the configuration file '/etc/rc.vlc'. The 'SERIAL' variable defines the
Smartio/Industrio or Rocketport boards to be used. The 'INTELLIO' variable defines the number IO ports
connected to one or more Intellio boards.
The card configuration is defined in '/etc/satnms.rc' and the variable SATNMS_SERIAL defines the
combination of interface cards. SATNMS_INTELLIO defines the number of IO ports connected to one or
more Intellio boards.
The following table shows the configurations which can be selected with the parameter 'SERIAL'. The table
uses the abbreviations 4-PORT, 8-PORT and ROCKET for Moxa Smartio/Industrio series and Rocketport
cards respectively.

The ports provided by these cards are named following a
, making it easy to link port names to
connector names.
Ports at Moxa Intellio boards are defined by means of the 'INTELLIO' Variable. INTELLIO must be set to
the total number of serial ports provided by the modules connected to Intellio boards. The VLC assumes,
that the first 32 ports are assigned to board 1, the next 32 ports to to board 2 etc. 'INTELLIO=0' tells the
VLC that there is no Intellio board in the system. Intellio boards may be combined with the 4/8 port boards
discussed above, however, the total number of serial IO cards in the VLC must not exceed 3. Intellio cards
