3.9] Can two Ethernet stations be directly attached with 10BASE-T?

Two Ethernet stations can be directly attached to each other, but

Ethernet network connection. The 802.3 specification refers to this
direct connection between two stations as a crossover function.

The crossover function is accomplished by simply wiring the receive
pins to the transmit pins:
