The Modem Does Not Auto-Answer the Phone
C: If necessary, make sure the software is
configured to auto-answer the phone.
A: To set auto-answer mode on from AT command
mode, type
ATS0=n
then press Enter. The
n
stands for which number of rings the modem
answers. For example:
ATS0=3
causes the
modem to answer on the third ring.
The Software Does Not Control the Modem
Properly or Can Not Detect the Modem
S: Make sure the software has been set up
correctly. Check the initialization string and dial
string.
C: Some TSRs (programs that stay in memory
after they are loaded) may conflict with the
communications software.
S: Try starting your computer without loading any
TSRs.
The Characters on the Screen Are Doubled
C: Both the modem and the software have the
echo feature turned on.
S: Since only one needs an echo, turn the
software echo feature off.
C: The remote modem is echoing your typed
characters.
S: Type
ATE1
then Enter at the command line.
Then turn off the software echo feature.
