S
SPXII maintains full backward compatibility with the existing SPX. The
interface is the same, but taking full advantage of SPXII requires minor
changes to user applications. TLI (Transport Level Interface) is the only
supported application interface to SPXII.
SPXII verifies and acknowledges successful packet delivery to any network
destination by requesting a verification from the destination that the data was
received.
The SPXII verification must include a value that matches the value
calculated from the data before transmission. By comparing these values,
SPXII ensures not only that the data packet made it to the destination, but
that it arrived intact.
SPXII can track data transmissions consisting of a series of separate packets.
If an acknowledgment request brings no response within a specified time,
SPXII retransmits it.
If a reasonable number of retransmissions does not get a response, SPXII
notifies the application that the connection has failed.
SPXII is derived from Novell’s SPX using the Xerox Sequenced Packet
Protocol.

Serial port
A port that allows data to be transmitted asynchronously, one bit at a time.
Typically, serial ports are used for modems or serial printers.
On IBM PC-compatible computers, COM1 and COM2 are asynchronous
serial ports.
Server console
Under NetWare Services, a device (/dev/osm), which is the default device on
which system messages are displayed. The output of these messages may be
changed to another device or file by changing the nwcm parameter
console_device.
If you want to have the messages appear on your current terminal when the
server is started, set console_device to /def/fd/1 as follows:
