Subject: Re: Modem info

I have been using this modem for about 8 months with *reasonable*
success.  It is missing two things:  a speaker and the S register.

The speaker I miss more than I thought I would.  It is annoying to
sit through several redials not realizing that the phone I am dialing
is busy.  Or worse, to mis-remember the number and finally pick up
the phone to hear someone going "Hello ... Hello?"

The S register is generally not needed.  However on the Hayes it
controls some things which can affect reliability of operation on
unusually strong or weak lines.

Conclusion:  I paid $69 for mine.  I would like the other features,
but I am fairly certain I would not like them several hundred dollars
worth.
