ago....
Router to hub or switch = straight through
Hub to switch = crossover
Think DTE DCE
Hhhmmmmm....... PC to PC = crossover does DTE-DCE apply? Anyone ever do the
old pin 2-3 reverse with a DB25, long before there was Laplink for PC's?
What was that old PC application we used for remote control? I had a quant
analyst used to drive me nuts who would read about stuff like this in
magazines and demand it for herself. Wonder whatever became of her? I made a
150 foot serial cable, strung it under the raised floor of the trading room
to a small office where this woman would go to do her thinking.
This was long before it occurred to me that you really don't need all 25
wires in a DB25-DB25 connection.

PS puzzled by the statement that sometimes you use a crossover in a router
to switch connection. Unless maybe it so happens that the switch port you
plug into has one of those X options and someone pushed the button by
mistake and no one noticed, or knew what the X port did and why.

Because...
sometimes cross wires work, sometimes they don't. If they don't, then we
need straight.
And sometimes straight work, sometimes they don't. And then we need cross.
But seriously, think about transmit and receive...
