Given the state of Hayes engineering, I certainly hope so.  For example,
take the brand-new "V-series Smartmodem 2400".

I use some of our modems for both dialin and dialout.  They sit there
waiting for incoming calls most of the time, but sometimes uucico or tip
use them for calling others modems.  Under these circumstances, you
would like the modem to be reset to a "standard" configuration after
each use automatically.  You can, in fact tell the Hayes to reset
whenever DTR drops and rises.  You can also tell it not to auto-answer
unless DTR is asserted - necessary for dialin use.  Unfortunately,
these two options are mutually exclusive - you can't have the modem
use DTR for reset unless you give up DTR control of answer.  The Telebit
does this fine.

If a modem is to be used for dialout, command recognition must be
enabled.  However, you do NOT want the "+++" command escape to be
recognized when the modem is handling an incoming call, or operating
in originate mode with uucico.  Unfortunately, there is no way at all
to permanently disable the +++ escape without turning off command
recognition entirely.  The Telebit provides two ways of doing this.

I just gave up on the Hayes for dialout use, and use the Telebit and
a Vadic va2400 exclusively.

At least the new Hayes models no longer support sending Morse code...
