- We've had this setup working between a 386 PC and a Sun 2/120 for ages.
-
- How come the transceiver ethernet connector of ELC doesn't work
- normally according to spec.? Sun ELC (4/25) and 386 PC won't talk via
- Transceiver ethernet null-modem cable anymore like in Sun 2.
-
- The error message in boot is simply 'le0 -no carrier. Transceiver
- cable problem'. Nothing helps - we've tried to hardwire differential
- signal 'Collision detect' both to 'no collision' & 'collision' too.
-
- The only difference to standard ethernet is ****pin 4****?? on Sparc
- Ethernet connector that is wired in addition to the usual pins
- 2,5,6 (gnd), 10, 13.
-
- I wonder what signal goes on that pin 4? The sparc works well when
- brought into usual network.
