USR modem

Does anyone know how to disable retrains (via a init-string) on a USR 56k pci faxmodem model # 5610

Why in the world would you want to shut off retraining? - Any change in the line condition and you'd lose the signal, get out of synch, experience extraordinary packet loss - basically, you'd cut your effective transmission speed to about 9600 baud.

I've seen the insides of SEVERAL telco central offices and I'm still amazed calls go through successfully as often as they do. Not because of a lack of skill on the part of technicians, mind you - those guys & gals are AMAZING, but simply because of the dozens of pieces of equipment the calls go through and the millions of connections involved in even the simplest call. What I'm trying to say is that if you turn off retraining in an environment where the connection conditions change from second to second, you're asking for trouble.

The only time I'd want to turn off retraining is if you are doing a direct modem to modem connection in the same room. Is that what you're doing?

I have serious doubts -

As to the original question - sorry - no, I don't have the needed AT commands handy - never tried to do what you're suggesting -

I would like to hear how it works out for you if you do get the right AT command.

I would think you'd be better served by finding the best local ISP that gives you the steadiest connection, that or just installing a NIC and a cable modem for some real speed unless you go with a DSL line which depends on your distance away from the central office feed.

Hey Axel the reason i want to disable retrains, is because i read an article in a gaming magazine about speeding up internet connections and they recommend disabling retrains but leave upshifts and downshifts enabled. The reason they recommend it is to prevent long time-outs due to total line renegotiations, and by leaving upshifts/downshifts enabled the modem can still adjust to adverse line conditions on the fly without full line renegotiations. When i download something i don't get a constant data stream but frequent intervalls(which can last for seconds) where no data is being transmitted. So i thought that disabling retrains might help.
