Sorry, I meant that I tried it on both Fedora 2 and 3 and got the same result. The LKA has: ati9 North America (01.00AEI2316\00000002\MODEM\TIA0578,TIA0602\56K EXTERNAL MODEM;C9) ati3 56K External Modem Serial s110701bA11 V2 V92cap Mercury The LKU has: ati9 North America (01.00AEI2316\00000002\MODEM\TIA0578,TIA0602\56K EXTERNAL MODEM8E) ati3 Actiontec 56K Hybrid Venus V.92 Serial s02.08.16iA07H V2 V92cap Mercury The "hybrid" might mean that the LKU is serial/USB. From what I can tell from modem-help.com, "Venus" means a Lucent chipset. Note that both have the same "AEI2316" hardware ID. I asked Actiontec support, and they just said that it was probably the lack of a driver for Linux -- no real information.

I installed an Actiontec EX560LKU external serial/USB modem and connected it to a serial port. The TD light remains lit and the modem will not respond to commands. Another identical unit behaves the same way. The modems work properly on Windows 2000. I also have an EX560LKA (serial only) which works fine. The Linux is Fedora Core 2 and 3. I even tried a null modem cable in desperation; the TD light goes out, but of course it still does not communicate. Any suggestions?
