                   D-LINK POCKET LAN ADAPTER POWEREXEC PORT REPLICATOR

    PROBLEM:        With D-Link DE 620 Pocket LAN Ethernet adapter connected to the
                    PowerExec Dock Box parallel port, D-Link diagnostics fails the
                    Register Test and reports the wrong type of parallel port:
                    unidirectional instead of bi-directional or EPP.

    CAUSE:          Incompatibility between the D-Link Ethernet adapter and the Easy
                    Port parallel port on the PowerExec Dock Box. There are
                    insufficient delays between the I/O accesses to the parallel
                    port mode registers.
