Loading the Asynchronous Card Firmware

7-2 Peripherals Configuration (R1001H) HP-UX version 11.00.01

Notice that the instance number (column I) for the asynchronous serial interface

card in the example is 1. The other instance numbers are for the three console

controller ports.

Instance numbers are assigned according to standard HP-UX operating system

protocols. If no instance for the card is found on the flash card during booting, one

will be assigned. If more than one asynchronous serial interface card is installed,

each will have its own instance number in class tty.

Loading the Asynchronous Card Firmware

The U450 and K118 cards are intelligent cards; that is, they contain firmware that

enables them to function. This firmware must be loaded onto the card when it is

installed for the first time, or when the system is rebooted. The needed files are

contained in the /usr/sbin directory. The files must also be reloaded if the

system door is opened and shut, or the ftsmaint disable and enable commands

are performed on it.

The downloadd daemon is automatically started at boot time. If this process is

killed or needs to be restarted for some other reason, use the downloadd

command to restart it. See the downloadd(7) man page for more information.

Under normal circumstances, the downloadd daemon will check the

/etc/stratus/download.conf file, and download the appropriate firmware

file automatically. Device access will fail if the asynchronous interface firmware is

not downloaded.

The downloadd daemon keeps log files in the /var/adm directory, in the file

/var/adm/download.log. This log should be consulted if problems occur.

Downloading the firmware to the interface card takes approximately 20 to 30

seconds.

Creating Device Special Files

Device special files for the asynchronous serial ports must be present in the /dev

directory in order to use the card ports. These files must be created using the mksf

utility.

NOTE

Appropriate device special files are created automatically when you

configure a modem or terminal through the SAM interface. This section
