In configuring an older 33.6Kbps US Robotics modem for accepting auto-dial-up calls into a router, here are a few items to know:
- Use 'at&f1&b1&w0&w1y0' to force the modem to speak at 9600 to the router
- use 'ati5' to confirm new communications rate setting
- I seem to recall that all dip switch settings are in the up position but for 2, 4, 8, which are down
