I have had notorious problems with Ubuntu and external modems, It has put me off for the moment until I can find a fix. I have tried 2 different external modems and both had sub 14.4k connection speeds. I think I tried some init strings and I tried setserial, both with no noticeable effect. If you do find a solution I would be very interested in it. :) Dean

Hi all,

<snip>

ALSO:

I am having some trouble with my external modem...

* The abridged version * Good connection using Win2K, SLOW connection using Ubuntu.

* Detailed version * Step1: To begin, I checked to see what modem I had via MiniCom: atz OK ati1 External Controller Ver1.20, CheckSum=617A OK ati3 TP560 Data/Fax/Voice 56K Modem OK

- So it is a (generic) 56K Modem.

Step2: I used Win2k to perform a speed test (it's the pc nearest to the phone line) Connected to http://www.jestreamgames.co.nz/speed/ Quite a respectable speed (43 K bits/sec)

Step3: I connected the modem to Com1 on my Ubuntu box, it connected, but the same test (on the same phone line) gave me 0.9 K bytes / sec!

I realize that the speed test is not going to be overly accurate, but I'm not concerned with getting an accurate speed measurement. I just used this method to get a comparison. btw - I did the 500k test.

Does anyone have any ideas / suggestions ?

Thanks Ivan
