how to know the modem connection speed under Linux?

Post by Jose Men » Sat, 07 Oct 2000 04:00:00



Hi,
does anyone know how to determine the connection speed of a dial up
session under Linux? I only get the baud speed of my serial port when i
report the CONNECT string, but i don't get the speed it negociates with
the remote modem.
When i connect with a windows it tells me the speed it has negociated so
i'm sure that Linux can do it too. Maybe it's an AT command but i don't
know which one and how to pass it after stablishing the connection.
Thank you.

Hi again,
In fact, I want to know which DCE speed reurns my modem when it connects,
becuase it always gives me theDTE speed.

Look in your modem manual for the AT command, in the old Hayes command
set ATW1s95=47 would cause the modem to report initial DCE connect speed
(and other things as well).  Add the chat option ``REPORT CONNECT''
and the pppd option updetach (or nodetach to be able to control-c pppd)
to get it sent to the terminal.

REPORT CONNECT may not work for an old version of chat and -detach may
be needed in an old verision of pppd.  Chat comes with the pppd source
package, and the latest pppd source package (2.4.0) can be obtained via
ftp at linuxcare.com.au in /pub/ppp.

1. Querying modem-to-modem speed of PPP connection.

I'm using Redhat 4.1.

Is there a way to query the modem-to-modem speed of an existing PPP
connection?  I know that I can send packets and do timings to
calculate this, but I'm wondering if there is some utility that already
exists which will give me this information.

By the way, I'm not interested in the speed returned by 'setserial',
since that's the speed of the port itself, not the modem-to-modem
speed.

Thanks in advance.
