When you power on your computer or reset the I-modem, the DIP switch
settings override the settings you may have made previously using AT
commands.
Note: The following AT commands are not changed by a power-on or
reset and must be changed manually: &Cn, &Dn, En, Qn, Vn, S0=n,
S14=n, and S67=n.
If you change the DIP switch settings while the I-modem is on, you can
avoid powering your computer off to make the new settings take effect.
Just send the I-modem the ATZ or the ATZ! command. (ATZ! is a “hard”
reset, which is just like powering the I-modem off and then on. ATZ is a
“soft” reset, which is like rebooting the I-modem and not removing
power.)
