The computer runs slower than usual
1. Close any open applications that you are not using.

Medium; or Medium to Low. This is in the SM56 Control Panel application. This option is
not available for the PCI modem.

You cannot enter tone selections successfully when calling tone-driven
applications
When dialing a remote system that requires you to enter selections using the telephone keys, such
as a voice-mail depot or bank-account information provider, you can lengthen the duration of the
tones your modem sends, so that the remote system can detect them better. To adjust DTMF tone
length, use the AT+VTDn command, where n specifies the tone duration.

The modem does not respond to AT commands
1. Ensure that your communications software is configured to use the same COM port as the

2. Reset modem parameters to default options by entering AT&F; then re-enter custom options.
3. SM56 builds after Build 50 require setting the S46 register to 23 before AT&T1 will perform
the Local Analog Loop(LAL) back hardware test.
