Titolo: Strani messaggi tra Kernel e pppd...ci riprovo!

Salve a tutti,
č da qualche tempo che seguo questo NG, e ho trovato tante risposte ai miei
innumerevoli dubbi e tante soluzioni ai miei problemi con Linux.
Ecco l'ennesimo dubbio:
se cambio da 57600 a 115200 una delle righe del file /etc/options, dopo il
collegamento con l'ISP leggo i seguenti msg nel file /var/log/messages:
Aug 20 09:28:45 rh61P75 chat[5286]: CARRIER 49333^M

Se invece nel file /etc/options metto 57600, nel file /var/log/messages
leggo:

Quello che vorrei capire, č cosa significano quei msg in piů quando nel file
options ho 57600.
Che vuol dire, che se metto 115200 non viene attivata la compressione del
PPP?
Grazie tante, č solo per capire.
Saluti.

 PPP?
Non lo so ma la velocita è riferita alla porta, quindi lascia 115200....
Ciao.

 Ciao.
cosi' a naso direi che il kernel sta cercando di cambiare la velocita'
della porta (io_ctl)
