Re: [Q] 56K US Robotics?
Would anyone know how to verify that I am connecting to Internet at 56K. I run Debian hamm + 2.1.78 kernel. I also have an USR 56K modem, and I am getting the following connect messages Feb 1 11:23:08 pequod chat[310]: CONNECT 33600/ARQ/x2/LAPM/V42BIS ^^ after my ISP started using digital modems to support 56K. -- Adriano -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Vladislav, You can use a chatscript of this type: ABORTBUSY ABORTNO CARRIER ABORTVOICE ABORTNO DIALTONE ABORTNO DIAL TONE ATZ OK ATDT123-4567 CONNECT \c ^M Then you will get the connect speed logged to /var/log/messages, although you may have to use the -v option to chat to make it log that.

Re: [Q] 56K US Robotics?
The answer to this is not as simple as it seems. First of all, I have observed that in both Win95 and NT, the connect speed reported can be, interchangeably, the DTE speed and the V.34 speed. What's the max DTE speed you've got your modem set for? I bet it's 56K, right? Now, since with wonderful M$ software there's no way to know where it's getting that data from unless you pay up $$$ for contract support, we can only conjecture at how it arrives at connect speed. As far as xisp goes, I don't use it and haven't looked at the source but since you say it's reported 31.2 and 31.2 is an actual V.34 speed (V.34 adjusts speed for line quality, but over a fixed set of speeds, not continuously) I'm guessing that it's getting it from the CONNECT message which the modem issues when it establishes a connection to the peer. The thing is, you can modify what will be reported upon connect by configuring the modem with AT commands. Who knows what Win95/NT gives to the modem to configure it. Based upon the above observations though, I would tend to believe that you are in fact connecting at 31.2. Disappointed? You're not alone. Did you read all those articles about this technology? Check out http://x2.usr.com/technology/overview.html and your ISP for more details. Vladislav Papayan x285 wrote: Hello, Would anyone know how to verify that I am connecting to Internet at 56K.

Quick solution: use ncftp to download a binary file from your ISP's ftp server. It will tell you the transfer rate after finishing the download. Some thoughts about connectspeed: You can't relay on the speed negotiated during connect. Here in germany, a stable connect is at most 46.000 Bytes/s. And some tests (www.cnet.com) say the same for the US. Most modems have some AT commands which tell them how risky(=fast) they should connect. If the modem chooses a too high connectspeed, errors will occur during transfer. This is no problem. The modem will decrease its speed. But you won't notice this as you can't ask a modem about it's current speed. The opposite case is possible as well. The modem will increase its speed on good connects. My guess about why you get 56k on WinNT: You use a USR modemdriver for NT. This driver sets the above mentioned risksetting very high. So you get a 56k connect. But the modem will decrease its speed very soon as errors during transfer will occur often. On Linux you use ATF to initialise your Modem. The F settings have a rather conservativ risksetting and you get a minor connectspeed. You could do a test: Download a somewhat big file form your ISP's FTP Server, one time using NT and one time using Linux. Then you can see if I am right.
