I can't remember if I posted this, or e-mailed it to the original
poster.  I tried searching backwards on the subject line, and if
I did post the article has expired here.  Therefore, my apologies
if you've seen this before.

I don't know why your modems are behaving as they are.  Some modems
have default settings in non-volatile memory, and it is possible that
the freek occurances that have been mentioned have corrupted that
memory.  Check your modem's documentation to see if this might be
the case.  If so, you should be able to configure the modem using
AT commands and save the configuration in memory.

As for a quick fix, you can disable auto-answer by setting the value
in register S0 to 0.  Putting the line "echo ATS0=0 > COMn" (minus
the quotes), where n is the COM port to which your modem is assigned,
in your autoexec.bat file should do the trick.
