Not really. Point-to-point on thin Ethernet (10Base2) is half-duplex only. All signaling shares a common path and full duplex depends on being able to transmit while receiving. It normally requires: 1. Direct connection via cross-over cable 2. Direct connection via point2point cable to a switch R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
