Modem Initialization Strings
To initiate a modem connection, the Solo E1 DSU sends +++ followed by
the Þrst modem initialization string. The Solo E1 DSU waits for the modem
response. The Solo E1 DSU waits for modem response so that it can guard
against the possibility of losing the characters right after the modem reset
command. After receiving the modem response, the Solo E1 DSU sends the
second initialization string (if programmed).
