[comp.sys.ibm.pc] modem picks up phone

chan@portal.UUcp (Jeff Chan) (07/28/89)

When my pc-clone is powered up, my 2400 baud hayes-compatible
modem insists on picking up the phone (hoping to get a carrier).
I don't want this; I want to be able to have the computer on
and pick up the phone and respond to voice messages.  How do
I fix this?

Sorry if this is too bush-league.  Please reply by email if
you have an answer to chan@portal.com.

Thanks,
Jeff C.

Thanks to those who answered my query about disabling the autoanswer
feature of my Hayes-compatible modem.   It seems that there is a modem-
internal register S0 that controls the number of rings before the modem
picks up.  

I haven't tried yet, but the consensus was that setting this register 
to 0 by using "echo ATS0=0 > COMn", where n is the modem's com port number,
should disable this.  Others also suggested seeking out a dip switch
which may do the same thing in hardware.  For now I will try the former,
and will investigate the latter when I re-find the modem documentation.

Again, many thanks to those who responded!
