genuse22 0 Posted January 31, 2005 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. Instead 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! Rod Share this post Link to post
Dapper Dan 0 Posted January 31, 2005 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. Share this post Link to post
martouf 0 Posted January 31, 2005 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?

genuse22 0 Posted February 2, 2005 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 Share this post Link to post
martouf 0 Posted February 2, 2005 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 ) [Edited by martouf on 2005-02-02 13:20:27] Share this post Link to post
martouf 0 Posted February 2, 2005 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. Share this post Link to post
