For information about AT commands, refer to Chapter 2, Using the AT

Command Set, in the I-modem Command Reference manual.

This DIP

Switch

Position Does this

1 ON (Default) Loads the configuration that is stored

in non-volatile memory (NVRAM)

OFF Loads the &F0 configuration that is

stored in read-only memory (ROM)

2 ON (Default) Acts on AT commands (smart mode)

OFF Ignores AT commands (dumb mode)

3 OFF No effect

4 OFF No effect

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.)
