That makes a VAST difference.  You should have been more specific.  :)

The manual clearly explains that the &F0 template initialises the modem
with software flow control defaults, while &F1 is hardware flow
control, which is the one you need to use.

That's the new internal PnP model, but with the earlier ROM code (the later
model is apparently buggy, and has problems with V.42bis lockups).

Refer to the Result Code chart in your manual, and use the X setting which
corresponds to how your modem works here, as some US/Canada Sportsters
don't recognise dialtone too well, while others don't recognise the busy
response.  For example, if your modem says NO DIAL TONE while attempting to
dial out, set it to X3, which disables that particular part of the code,
and blind dials instead (IOW, it doesn't look or wait for dialtone).

As I said before, If you're issuing AT&F1X3&W correctly whilst in
terminal mode, but the ATI4 screen still shows X4, your modem is faulty.

You should also only be using that init string once in terminal mode BTW,
then calling it from Telix with ATZ (reset to stored NVRAM values).

V.34+ can be too aggressive with some other V.34 modems, and the only fix I
currently know is to disable the 3429 symbol rate on your USR for those
calls to boards where you know it's a problem.  To do this, you simply
change your dialling string for those boards to ATS54=96DT.  When your
modem resets after the call, it will also reset that register to its
default S54=64. 

Type ATS$ for more info re the undocumented register values.
