Ethernet Connection Works With/Without Crossover Coupler ?

[abtemp]

Hello,

I have a Cat.5e Ethernet crossover coupler, pins 1-3 connected, pins
2-6 connected, however my PC to 4 port switch connection works whether
or not I insert the coupler with an extra straight through cable. I
have verified coupler and cable wiring with a continuity tester. The
situation also applies for my laptop. I am however unable to get a PC
to laptop connection working using two straight throught Cat.5e cables
and the crossover coupler. Do some Ethernet devices such as the switch
have auto pin sensing/selecting ? Why does the PC-laptop connection not
work (it starts to register, however no packets transfer, and then the
connection fails).

Any ideas ?

Thank you
