While the PPP connection is active and owns the lock on that tty... I was trying to write exactly that stuff, but it doesn't seem to work.

Re: determining serial link speed?
I have had an intermittent problem with my USR connecting at 14400 instead of 28800 and solved it by changing the connect string that chat was expecting from "CONNECT" to "CONNECT 2".

Re: determining serial link speed?
I am not sure how this would work with a PPP connection open (and thus, the device locked for PPP use), but USR modems support an AT command, ATIn, where n=0-7, and ATI6 returns link diagnostics, including current transmit and receive speeds (I have seen it working before, and it is probably the information desired here). The question is, how to access the modem to send AT strings while online (rather, how to insert "+++" into the data stream to the modem, then the AT command, get the response back, and put it back online). -dh Brian K Servis wrote: > > [EMAIL PROTECTED] writes: > > > > > >On 07:06:32 Lawrence wrote: > >>>Martin Steigerwald wrote: > >>> > >>> Hi! > >>> > >>> Is there any easy way to find out, what speed my modem connected to > >>> the ISP?

There is also a &Nn which sets the restricts the connect speed or when used in conjuction with &Un works as the ceiling connect speed, thus creating a connect speed window.

Re: determining serial link speed?
Oh, mine _connects_ at 33.6, but then it renegociates and falls back to 21.x in one direction and 24.x in the other. So telling what it connects at isn't necessarily useful. I know what is going on because I have one of the external Supras on the other end of the connection and it reports the speeds on the front panel. I use minicom to connect once in a while just to check what the modem says when it connects.

Re: determining serial link speed?
besides checking what speed you set in your ppp.options file, run pppstats -i 1. This should show you how much data is being transfered per second. you should have it somewhere in the high 2000's. run an ftp session from a closs machine to test it.
