Actiontec External - need v44 AT command
Just started using Linux (Debian)- I now have it on 3 systems. Per advice here, I got an Actiontec External modem. I am using an Earthlink dialin number that supports V92, but at connect time V44 is not started.

V42 is started.
I need the Actiontec AT command to enable V44- I have emailed
Actiontec TS - no reply. Thier docs only show v.90
enable/disable. Help!

So you are unable to get online?
I've tried looking for information on your problem but am coming up empty. I have emailed Actiontec with request for assistance before. It usually takes them a few days but they always got back to me. How long have you waited for assistance?
Are you using kppp or wvdial? Can you post the output it is giving you? Have you contacted your ISP to see if they have any suggestions? If you're having this problem it'd be difficult to understand if none of their other customers have ever had it.
Actiontec modems are very widely used and have always given me good service. This is the first time I've ever heard of anybody having difficulty with one.
I wish I understood the problem better. I'll do somemore research.

I'm finding the phrase "ITU V.92 and companion V.44 standard".
Best I can tell, the modem should auto-negotiate this compression protocol
with the modem at the other end.
Default values (see Actiontec manual) appear to have the modem attempt the
highest data rates supported by line conditions.
genuse22: are you trying to squeeze a few more Kbps out of your link?

Thank you Dapper Dan. Was using KPPP, config'ed WVDIAL and here's the output:
--> WvDial: Internet dialer version 1.54.0
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: at&fw2s109=2s38=1s37=14
at&fw2s109=2s38=1s37=14
OK
--> Modem initialized.
--> Sending: ATDT2024402
--> Waiting for carrier.
ATDT2024402
CONNECT 28800 V42bis
(snip)
[end output]
Note the V42bis should show V44 instead. Tried to contact Earthlink TS but their TS email server has been down for a few days (very rare!). Earthlink TS previously identified this dialin number as V92 compatible.
Any suggestions appreciated. Rod

ok, you've turned K56flex off (s109=2) and set max incoming rate (s38=1),
but you've set max outgoing rate to a fixed 21600 bps (s37=14).
why set the outgoing rate to anything but auto (s37=0) ?
I know there's a "suggested" init string in the manual, but my experience tells me
not to trust it very much. I would take it as an example of syntax.
I also know the initial handshaking at both ends can go weird if it doesn't
progress through all of the "expected" states (including trying to negotiate
an unsupported protocol (like K56flex)).
Have you already tried s37=0 and s109=1 ?
(I encountered a source here which gives a Lucent chipset recommendation
of trying s38=0 )

by the way, found this: http://www.modemsite.com/56k/trouble.asp
looks like a great resource for finding the nittiest of the grittiest
info on the AT commands applicable for your modem.
