How do or what do I need to add PCI / PCIe (PCI Express) parallel ports add-on adapters to OpenServer 6.0.0? OpenServer 5 could see PCI slots but OpenServer 6.0.0 (Original CD or the Re-cut one) required a maintenance pack to be installed? Is this right and how do I check to see if these work? (2 Replies)

ports(7) Miscellaneous Information Manual ports(7)
NAME
ports, port_names - Device (tty and lp) names for serial and parallel ports
SYNOPSIS
Default Serial Ports:
/dev/tty00
/dev/tty01 (not present on a single-port system)
Parallel Port:
/dev/lp0
DESCRIPTION
AlphaStation and AlphaServer systems provide one or two 9-pin serial communication ports. These ports are usually labelled 1 (COMM1) and 2
(COMM2), but they may be identified by different icons. Using the appropriate serial cable and terminator, you can connect a serial
printer, external modem, or character-cell terminal to a serial port. Most AlphaStation and AlphaServer systems also provide one parallel
port, for use with a parallel printer.
When you add a device to your system, the installation documentation may instruct you to map the device pathname to the port. These
devices are located in the /dev directory.
For serial-line ports, the two default device pathnames are: This pathname always maps to 1, COMM1, the lowest port number, an icon for a
terminal console, or the only serial port (on a single-port system). This pathname always maps to 2, COMM2, the next numbered port, or (if
one serial port is labeled with an icon for a terminal console) the remaining serial port.
If your system hardware has been extended to include additional serial ports, the pathnames /dev/tty02, /dev/tty03, and so forth, may also
be available to you. However, most systems have only /dev/tty00 and /dev/tty01 as the device pathnames for serial ports.
The one parallel port on an AlphaStation or AlphaServer may be labeled with the word printer or a printer icon. On some systems, the paral-
lel port may not be labeled. The device pathname for the parallel port is /dev/lp0. Currently, Tru64 UNIX does not fully support parallel
printers, so fewer devices are connected to this port as compared to serial ports.
If you are connecting a terminal console to your system, it must be connected to the serial port mapped to /dev/tty00. For other serial
devices, it does not matter which of the serial ports you choose for the connection. For example, suppose you are setting up a system that
has two serial ports, labeled 1 and 2. You intend to use a serial-line terminal rather than a workstation monitor as the system console and
also want to connect a serial-line printer to the system. In this case, you must connect the terminal to the port labeled 1 (with the
device pathname /dev/tty00). Therefore, you must connect the printer to the remaining port labeled 2 (with the device pathname /dev/tty01).
If, for the same type of system, you intend to use a workstation monitor as the system console, it does not matter which serial port you
use for a serial-line printer or modem. In other words, you can connect the printer to either port 1 (with pathname /dev/tty00) or port 2
(with pathname /dev/tty01). When prompted to enter a /dev/tty** pathname by the lprsetup script or the Print configuration tool in the CDE
Application Manager, you would specify /dev/tty00 if you connected the printer to port 1 or /dev/tty01 if you connected the printer to port
2.
