Brian: I have been following this thread, but now have a question. You are dialing 4800 to several other modems and now you wish to use the same modem to connect at 9.6. Connecting via 4800 is a pretty old standard, What type of modem are you using. I suspect you are using a half duplex modem that support the bell 208 a/b standard. I also suspect that the new modem you wish to talk to supports a v.32 compliant standard. What I suspect here is that the modem you have, and are currently using for BSC @ 4800 is not going to work for 9600, no matter what you do. cjg Carl J.

My dilemma is that our physical modem is set at 4800 bps and set not to change. All other systems we dial out to are to specific numbers that have modems on the other end set to 4800 bps and set not to change their communication rates. Now all of a sudden I have a requirement to dial out to another system at 9600. Their modem is setup not to negotiate a rate (it will only connect at 9600). I was hoping to be able to change the line description to 4800 or 9600 bps which would send the control codes to my modem and reset it's connection speed respectively. No such luck huh? Thanks for your help. Brian Ellis Pat Barber wrote: > > Generally speaking, the software will have no effect on line speed.
