You could try iptraf, and choose statistics. It will give current throughputs and other details. pppstats might also help, but i have no ppp interface to test it on, so try it and see. Other thing (overkill maybe) would be to use MRTG and snmp to graph the ppp interface. Of course, you may also want to listen on the phone line for excessive noise/static/cross-talk. I was just recently getting connection speeds like 2400bps, 9600bps, 16000bps, and picked up the phone and had lots of static and great cross-talk across out two lines. Water in the connector and touching wires, which Telecom fixed quickly, and now its back up to its normal speeds. > Am I missing something obvious?

How about AT W2 which generally changes the connection that the modem reports on to the DCE speeds. But look for your specific one since it may differ http://www.modemhelp.net/quickref.shtml I also like \V1 (verbose) on my dynalink. Gives detailed connection stats (v90 or v34 connection, up/down bps) Also remember your modem can retrain, so its not that useful over a longer connection period. Then look in /var/log/messages, for wvdial's messages from memory. Daniel
