Titolo: Vi SFIDO a darmi una spiegazione (per i più pazienti!!)

Ciao a tutti. Vediamo se c'è qualcuno in grado di darmi delle
spiegazioni su ciò che accade al mio modem nelle connessioni.
Qui di seguito invio il file del mio modemlog.txt generato dal modem e
controllato da Netmedic.
Il modem in oggetto è un Motorola Voice Surfr 56K upgradato allo
standard V.90.
Ho provato diverse stringhe di configurazione da me costruite dopo
avermi studiato i manuali dei comandi AT, e riesco a far andare il modem
a v.90  senza però la compressione software e il controllo errori.
Diversamente riesco sempre a farlo connettere non a V.90 (almeno io
penso di no) con la compressione dati e il controllo degli errori.
Sapete dirmi perchè
Ecco le stringhe:
--------  AT+MS=12,1\N3%C3%TCBS31=2
Abilita la velocità effettiva (S31=2)
Abilita lo standard V.90 ma non funziona (+MS=12,1)
Abilita la compressione e il controllo degli errori (%C3)
Abilita l'eliminazione della Blacklist (%TCB)
Abilita la compressione dei dati

Stesso discorso.
Io penso che tu abbia avuto sempre delle connessioni in V90.
Ma senza stringhe che cosa succede? Hai dei problemi?
