Make sure to get hold of a USR manual.  Reason:  USRs, generally,  
use the ATZ and ATZ1 commands somewhat differently from other  
modems.

i.e. in short:-

USR modems restore the port speed that was in use when the AT&W
command was issued (saving the profile) and that port speed is
restored in the modem when ATZ is issued.  e.g.:  With your port
speed set to 57,600, you issue the following command:

AT&F1&W^M.

You then change the port speed to 38,400, and issue the following:

ATZ1^M.

The modem will now be configured to expect a port speed of 57,600.
Your PC port speed is 38,400.  If the modem now receives a call, it
will send RING at 57,600bps, and your program will _not_ see the
RING, because the port speed is mismatched.  If, however, you send
_any_ AT command (except ATZn), the modem will re-configure to the
current port speed (38,400) and will operate normally.

The rule:  configure the modem and save the profile at the _same_
port speed you intend to use with your software.

Get the idea ??

TTFN,

Archie
