Trasmission Problems With Terminal Adapters

Support knowledgebase (thallma_ta_receive-all)
Applies to

SuSE Linux: All versions

Symptom

Either you experience trasmission problems with your terminal adapter or the connection works smoothy only when you reduce the connection speed between your terminal adapter and the provider.

It may also occur that your terminal adapter hangs up after a few seconds.

Cause

Your system does not accept data packages labelled as bad frame. This is shown e.g. by the following message in your /var/log/messages:

Oct 4 01:47:16 pandora kernel: ppp: frame with bad fcs, length = 6
Oct 4 01:47:16 pandora kernel: ppp: bad frame, count = 6
Oct 4 01:47:16 pandora kernel: FF C0 00 21 BE 7B

Solution

Insert the following line in your/etc/ppp/options:

receive-all

Note: This approach works with terminal adapters only, but not with modems!
