Description Barry K. Nathan 2003-06-23 07:54:53 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030619

Description of problem:
redhat-config-network lets me set the modem volume to "Very High", but this is
not compatible with my modem and prevents a successful PPP connection from being
established.

Version-Release number of selected component (if applicable):
redhat-config-network-1.3.0-1

How reproducible:
Always.

Steps to Reproduce:
1. Configure a D-Link DMF-560TXD for "Very High" volume.
2. Attempt to establish a PPP connection (right now, that also means working
around bug 97845).

Actual Results:  (An excerpt from /var/log/messages.)
Jun 22 18:36:49 i5000e kernel: PPP generic driver version 2.4.2
Jun 22 18:36:49 i5000e pppd[2366]: pppd 2.4.1 started by root, uid 0

Jun 22 18:36:51 i5000e wvdial[2388]: stdin not read/write and $MODEM not set
Jun 22 18:36:51 i5000e pppd[2366]: Connect script failed
Jun 22 18:36:52 i5000e pppd[2366]: Exit.

Expected Results:  Successful PPP connection.

Additional info:
It would be nice to have some kind of warning in redhat-config-network, or
something like that, IMO.

The obvious workaround, of course, is to reduce the volume to merely "High."

Comment 1 Barry K. Nathan 2003-06-23 07:57:14 UTC

Clarifying "Additional info": I mean it would be nice to at least have a warning
that "Very high" is not compatible with all modems and may cause a connection
failure. (I might be able to code up a patch to do that, if there's a chance it
might be accepted.)

Comment 2 Harald Hoyer 2003-10-27 13:15:54 UTC

ATM was the wrong AT sequence... ATM1L4 would have been the correct init string..
