**I know dialup is old, but so am I**
Cliffs: Working modems would error out or not connect on new build. Lockup on dialup disconnect when I got that far. Shutdown froze at saving settings and reboot showed Error 678 after handshake from then on.
Fix (at least it's working now) was to limit modem and connection speed to 57600, disable hardware flow control, error control, and compression AND Limit buffers one notch for transmit and recieve. This info came after 5 days of misery, so use it if you can.
Cliffs over.
This info evidently has been known (?particularly for USR modems?) since 2001 or so, but I was happily using A 700 Mhz Athlon until last Wednesday and had only advanced to Winxp SP1 recently. I had several working (so I thought) modems.
I figured I'd take my upgrade pain all at once, so I got a MSI K9ngm2-FID, an AM2 Athlonx2 3800, and 1 Gb DDR2 corsair value. Other than needing a better power supply to boot up, this all went surprisingly smooth (I referenced the excellent thread on K8ngm2-fid in the motherboard forum here) until the dialup acted up. I noticed that there was no seperate "Dialup networking" icon in network connections as there was in SP1. I assumed (<look out for that word) that my problems were associated with Nvidia drivers firewall or NAM even though I never installed them. Then I started playing with all the networking setting, enabling and disabling the LAN in bios and otherwise digging myself a nice deep hole which I wallowed in for 3 or 4 days.
After all, these modems had worked in AMD and Intel machines from 333Mhz to 2.4Ghz, and with Win98 to Winxp SP1. I finally found the answers about 6 pages in in several old threads on old forums and cust. reviews (dated 2001 and 2002) when I googled "usr modems xp sp2".
I added this thread because when I had searched anandtech about this, I found nothing helpful.
