We must proceed to the verification of your modem. When there is a node free
to log on, this node will only accept 2400 Bps+ modem WITH error correction
like MNP, V32, V42, LAPM, HST...

This verification don't take place when ALL nodes are busy.

Choose one of these free node(s) to call the bulletin board.
At the end of this list, the modem will hang up.
