With my ZOOM modem, ATX4 reports all responses, but the manual
isn't clear if it means DCE (modem-modem) speed or DTE
(computer-modem) speed. I blieve DTE is the most commonly reported
value. ATW0 reports DTE speed only; ATW1 reports DCE speed, error
correction protocol and DTE speed; ATW2 reports DCE speed only. If
the -v option is set in the chat command line, this response appears
in the ppp.log file. An excerpt from my ppp.log follows:
May 2 14:37:51 bobspc chat[199]: ATDT3350566^M^M
May 2 14:37:51 bobspc chat[199]: CARRIER 26400^M
May 2 14:37:51 bobspc chat[199]: ^M
May 2 14:37:51 bobspc chat[199]: PROTOCOL: LAP-M^M
May 2 14:37:51 bobspc chat[199]: ^M
May 2 14:37:51 bobspc chat[199]: CONNECT
May 2 14:37:51 bobspc chat[199]: -- got it
May 2 14:37:54 bobspc pppd[192]: Serial connection established.
I use ATW1, but this report doesn't seem to include the DTE speed
(which is 115600).

Note the above log fragment. My ZOOM modem reports Carrier
<speed> before it reports the CONNECT.
