My "new" used Courier V. Everything 56K V.90 Cannot connect with any ISP UNLESS V.90 is first disabled. Here's the readout from diagnostics:
Product type US/Canada
So, it appears the unit has been upgraded and is up-to-date, ready to perform. I downloaded and installed the latest INF file: MDMCRV90.INF.
My own ISP does not support X2, and I cannot connect unless I first disable V.90. When I do, here's the result:
CONNECT 31200 / ARQ/V34/LAPM/V42BIS
However, here are connects for two local ISP's who do support X2. Again, I must disable V.90 in order to connect at all, but when I do, I get much higher connect speeds:
CONNECT 41333 / ARQ/x2/LAPM/V42BIS
The typical "56K" higher connect speeds for those ISPs who also offer x2 seems to indicate that this USR Courier still has its original x2 56K capability, but for some reason, when the modem was upgraded to v.90,
Ever hear of a "so-called" v.90 modem that acts like
Is it time to send this thing back, or is there a way to "force" the v.90 protocol to start behaving itself? Are there additional diagnostics to
Thanks for any insight.

Hello Bruce, it seems we both have the same type V Everything ISA modem.
Mine also is the 25 MHz clock type and has been upgraded to the same "latest" Supervisor rev 7.3.14 of 3/13/98
Mine "apparently" connects at V90 as stated in the modem log (below) but my problem, if you can call it that is that it always connects at 45,333 no matter which ISP I connect with.
I have three ISP accounts and none are "free" and all three support V90.
When I connect to any of the same ISP's on my wife's machine which uses a Diamond Supra Express external modem, the connect speed is either 48,000 or 49,666.
Here is a modem log of what I have:
04-27-2001 05:05:16.82 - Courier V.Everything INT PnP (V.90&x2) in use.
You may want to compare your log with mine and see what differences there may be.

Allow me to clarify:
My Courier V Everything is an external model. The problem is that despite the fact that it has apparently been upgraded, it cannot connect at V90--under any circumstances. With V90 disabled, it will connect at V34 or at X2 if that protocol is offered.
The modem logs which "Daddad" obtains are identical to mine since they use the same INF file, except I must add the additional command, SEND: ATS58=32 to disable V90. Then when I connect, my Recv line reads: CONNECT 31200/ARQ/V34/LAPM/V42BIS.
By contrast, with my SupraExpress 56Ke dialing into the same ISP number, I always get V90 connects in the range of 40-46K. So, right now a connect of "only" 45333 which Daddad obtains with his own Courier looks pretty good to me. I would be willing to trade modems in a flash-so to speak.
The bottom line appears to be that V90 is defective in this modem and cannot be cured short of reflashing the unit and hoping that will work.
Additional Information 04-27-01:
Thinking that the earlier V.90 upgrade had not loaded properly, I attempted to reflash the modem, using both the older code and the current code. Both attempts failed through "Error (15) Handshake Failed."

And what happens when you have V.90 enabled?
What does your y11 look like?

Thanks for responding.
Unfortunately, it's been impossible to get V90 diagnostics because the modem will not connect at V90--under any circumstances--no way, no how, nada, zip, zero, zilch . . . .
Here's the aty11 I did run with V90 disabled:
Note: I've pretty much exhausted my own troubleshooting on this project, and now would be the logical time to turn this project over to the USR techs back at the factory--that is if it were a newer unit. As it is, I have only $55 invested in this supposedly upgraded 1994 unit; the seller has generously agreed to take it back and refund my cost. So, I'm looking for a newer modem. Thanks for the help.
