Has anyone ever gotten the TDR function of the Micom NI5210 card to work? I've tried it using both thinwire and transceiver connections, opens, shorts and good connections (plus disconnected xcver cable) and the TDR status returned is always 87FF which is , ethernet OK. Anyone have any ideas? Brad Clements bkc@omnigate.clarkson.edu

PC/TCP's NI5210 driver implements the TDR function, and I've tested it, so the hardware is there. Check your code carefully against the Intel handbook for the 82586. I don't think it has anything to do with jumpers on the card. James VanBokkelen FTP Software Inc.

Recently I put together a driver for an Ether-board that uses the Intel 82586 controller. As part of the software initialization I had it do a TDR check. It was useful for testing the cable, and more importantly, the drop cable and connectors. However, there were circumstances where the TDR check failed -- mainly on broadband networks and over-extended Ethernets. If you do the TDR it would probably be useful to add an option to bypass the test for those nets on which it fails but not as a result of an error. --karl--
