[comp.sys.ibm.pc.hardware] Ring detect problems on Everex modem

charlie@hp-lsd.COS.HP.COM (Charlie Duke) (09/24/90)

   I am having problems with an Everex 2400b internal modem.  The modem works
very well in all modes except that the ring detect does not seem to function.
I have, briefly, RTFM but am unable to find a test utility that will test the
ring detect specifically.  Did I miss it in the manual or does anyone else
know a way I can confirm if I have a hardware problem or a configuration
problem?  I am not absolutely positive this modem has ever had a
functioning ring detect (thus it could be a configuration setting I don't
know about).
   I am running an HP Vectra 286 ES/12 with DOS 3.2.  The ring detect is
disfunctional with both Procomm and Kermit.  The modem will answer with an
ATA command.  It just doesn't seem to be capable of detecting the ring, and,
therefore, will not automatically answer the phone.  Cables have been changed:
no effect.  ATS0=1 has been issued and apparently understood by the modem.
  Thanks in advance.
