[cctalk] Trouble with DEQNA adapter

Hi all, This may be a dumb question but I am a bit stumped. I can't seem to find any helpful info in the manuals. I have a DEQNA installed in my 11/23+ and I have run a NETGEN using the QNA driver. When NETINS runs I start seeing messages like these on the console: Event type 5.14, Send failed Occurred 19-DEC-24 09:30:11 on node 10.1 (TYCHO) Line QNA-0 Failure reason = Collision detect check failed So obviously the link isn't working, but I find nothing helpful about where to start looking regarding the failed collision detect check. The line is on: NCP>show line qna-0 status Line status as of 19-DEC-24 09:36:31 Line State QNA-0 On I have an Ethernet transceiver (I have 2 and have tried both, they worked last time I used them) connected to the DEQNA harness, and a cable connecting it to an old 10Base-T hub. I know that hub works because I have a couple of other systems (OS/2 laptop and an AS/400) connected to it. So does anyone have any ideas of where I can start? Thanks in advance! Peter
