Yes, all this is correct, 'CONNECT...' string is the same as in MS Win. Thanks!

On speeds lower than 4800 it looks odd as I can not talk to modem on such speed. -- Mikhail Kolesnik ICQ: 260259143 IRC: mike_k at freenode/#crux, rusnet/#yalta Jabber: mike_k@xxxxxxxxxxxxxxxx NIC handle: MKK83-UANIC - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
