Parallel Port Performance - Xircom POCKET ETHERNET ADAPTER III User Manual

PAfMUEL PORT PERFORMANCE
The type of parallel port on your computer can significantly affect the
performance of the Pocket Ethernet Adapter III. If your Pc's parallel port
supports bidirectional mode, you can expect an improvement of up to
50% in the input transfer rate over
a
standard non-bidirectional parallel
port. If your computer supports Enhanced Pardlel Pott (EPP) technol-
ogy, data will be transmitted through the Adapter at three to four times
the rate of a standard parallel port. All Xirmm LAN Adapters are compat-
ible with Enhanced Parallel Port technology.
A
utility program
is
supplied
with the Pocket Ethernet Adapter
1 1 1
to enable EPP mode.
See
the
Confsgurution and Diugn- section for detailed instructions on its use.
Some PC designs allow the parallel printer port to be switched between
bidire-ctional and non-bidirectional modes of operation, while others
support only one mode. To find out if your parallel port
is
switchable, or
if
it is
EPP-compliant, refer to the user documentation for your computer
or contact the computer manufacturer.
