flexfax: "MODEM input buffering disabled"

Hello,

I got help with my problem of the fine strokes, that my modem
faxes sometime in the middle of a faxsimile. My /var/log/messages
reads:

Nov 10 17:48:12 rex FaxSend[541]: MODEM input buffering disabled
Nov 10 17:48:12 rex FaxSend[541]: SEND FAX: JOB 17 DEST 01013
02213494359 COMMID 00000112

Can somebody tell me where I can enable "Modem input buffering" ?
I have already commented in and out the config-lines in config.ttyS1
that appear to have something to to with flow control.

Thank you.

Ekkard



by the way:  If I comment in ModemSoftFlowCmd there appears an error in
/var/log/messages:
