First, the card must be made known to VMS through the firmware ISACFG utility.  Once the serial cards and ports are defined within the configuration file, the exact ISACFG invocations to be used will be written to the emulator log file along with the associated VMS 7.1 and higher configuration commands.  After creating the configuration file, start the emulator and type “exit” at the >>> prompt, then open the log file in a text editor to determine the correct set up commands for each Digiboard card.  The following section of log file was generated from the configuration code shown earlier.

00011.78: Digiboard multi-serial card configured.
00011.78: Firmware configuration commands:
00011.78:    >>> isacfg -mk -slot 1 -dev 0 -etyp 1 -enadev 1 -handle DIGI
00011.78:    >>> isacfg -mod -slot 1 -dev 0 -iobase0 100 -iobase1 108 -iobase2 110 -iobase3 118 -iobase4 120 -iobase5 128 -irq0 15
00011.78: Add these lines to SYS$SYSTEM:SYS$USER_CONFIG.DAT:
00011.78:   device          = "Digiboard Serial Port"
00011.78:     name          = TX
00011.78:     driver        = SYS$YSDRIVER
00011.78:     adapter       = ISA
00011.78:     id            = DIGI
00011.78:   end_device
00011.78: Add these lines to your startup procedure:
00011.78:   $ mcr sysman io connect /vector=60 /driver=sys$ysdriver txa1:
00011.78:   $ mcr sysman io connect /vector=60 /driver=sys$ysdriver txa2:
00011.78:   $ mcr sysman io connect /vector=60 /driver=sys$ysdriver txa3:
00011.78:   $ mcr sysman io connect /vector=60 /driver=sys$ysdriver txa4:

Log file output providing the firmware and VMS commands required to complete the configuration of the serial ports.  These lines will appear near the beginning of the Avanti log file.

 

Using the commands provided above, the following console commands define the first serial card.  These commands only need to be entered once.  Their settings are retained in the Avanti configuration's .nvr file.

>>> isacfg -mk -slot 1 -dev 0 -etyp 1 -enadev 1 -handle DIGI
>>>init
>>> isacfg -mod -slot 1 -dev 0 -iobase0 100 -iobase1 108 -iobase2 110 -iobase3 118 -iobase4 120 -iobase5 128 -irq0 15
>>>init

Cut and paste the ISACFG commands from the Avanti log file  to the console to define the serial card in the firmware.

A "sh config" or "isacfg –all" command can be used to confirm the presence of the ISA card definition in the firmware.
