PPP works with a modem and not with another one
Hello,
Before starting with my problem : I sent the same message to the mgetty mailing list a few days ago, but this list do not seem to be active any more (no message at all on the list since I registered). If someone knows an appropriate place to send my question, I would appreciate the advice... That said, let's go : I have an embedded system with linux OS + PPP + mgetty, on which I establish a dialup link from a windows machine using pap authentification. That worked well until I had to change MODEM model. I had a socket modem based on a connexan chipset, working well, and the new one is based on a silabs chipset. Of course I tried different hardwares (modems and embedded mother board) to be sure it is not because of a faulty component. Here is what I have done and noticed : I activated mgetty and pppd log. Without changing the init string, mgetty don't even call pppd : Code:
[...] So I found an AT command that disables protocol reporting (AT\V2). It works better, because mgetty catches user='/AutoPPP/' and calls pppd. but that is still not enough, pppd log show me that the LCP negociation fails : Code:
[...] Code:
LCP: timeout sending Config-Requests Any idea would be appreciated. details : OS version : linux 2.4.19 mgetty version : experimental test release 1.1.27-Oct21 modem : telecom design, model SMSIL, based on Si2493 chipset from silabs (http://www.silabs.com/pages/Download...portDocLibrary) I can attach logs and config files (mgetty and pppd) if it helps.
