Conexant D480 MDC V.9x modem problem

Question

I recently bought two Latitude D600's and both computers have a problem with the modems handshaking with our BBS modem (USR external V.90 56K). Everytime it goes to handshake it gets stuck and makes a really funny noise. I have tested the modems with your test site in hyperterminal and they both work fine. Is there some sort of string that I need to put in to make it compatible with the USR modem? Every other modem I use works except these. Please help.

I haven't even gotten a response from Dell on this issue.

I am having this same problem with all of our D600s. The modems work when connecting to a 28.8 analog modem, but they fail on a 56k digital modem pool. On the 56K, they will make the connection, start the handshake, and then stop...eventually producing an error that says the modems on the remote computer are out of order. (However, all other modems connect just fine.)

Has anyone found a solution to this problem? Any help would be appreciated.

I fixed this problem by replacing the dial-in location with a new V.92 Modem Blaster. I don't think the manufacturer is the problem, I think the problem is that the new V.92 modems do not handshake properly with the V.90 modems. I haven't had a problem since I replaced the modem. Good Luck.

In fact, I have disable V9x on the conexant modem. I have put +MS=V34 as additional init string on the conexant modem and it works (at 33,6 but it works)

There is a new driver file name R72369.EXE which fixes this.
