I work for a small ISP, and we're having trouble with a customer using
a US Robotucs 56k fax int pnp. I'm fairly certain it is line trouble,
because the modem worked fine at another location, and the location it
is at right now is several miles from town.

I have told that she will need to get a hold of the telco to get the
line checked out, but I tried to disable V90 in the meantime.
Unfortunately, the string I have for US Robotics modems (S32=66) does
not work on this modem. Does anybody here have the correct init
string to disable v90 on this breed of modem.

If you are going to contact me by email, please the address below, and
not my address above. That's a spam trap and spends most of its time
being full.

If this is the "softmodem" made with the Conexant chipset, try the usual
+ms=v34,0 to get it to use V.34 instead. If it is the standard USR, the
S32=66 should work but you can also try s32=98 (disables both x2 and V.90).

"In a New York minute, everything can change..."

if you have a USR Courier, use this command: ATS58=33 (X2 off / V.90
off)
else if you have USR Sportster or Telepath 56K with X2 try using:
ATS32=98 as recommended before
else good old +MS=V34 should do the trick for the conexant based modem
hmm you can use hyperterminal to connect, then issue the command
ati11, this will run a diagnostic hmm if you find that SNR (dB) is
low, then you know there is line noise or poor quality, here is an
example for you

Thanks for all the help! I wasn't even aware that US Robotics had
ever put their name on a Conextant modem. The customer will be very
pleased.

Hell with USR it is hard telling what is inside the plastic.
