Il Log di Windows 98 riporta degli errori durante la connessione:

Il modem funziona però correttamente se mi connetto con un altro provider

C'è qualcosa che posso fare?
Ringrazio anticipatamente.
Ciao!

Per migliorare la qualita` della connessione puoi provare ad 
aggiungere nelle impostazioni addizionali S27=65 oppure S27=65S15=136
Ciao,
