OGo Back Online

You can use the O command to bring the modem out of command mode and back into online mode. The O command reverses the result of entering the escape code. The O command brings the modem into whichever online mode (originate or answer) that it was in prior to entering command mode.

Remote Configuration Commands

When you are online with another Multi-Tech modem, you can issue AT commands to it by sending a remote configuration escape sequence. The remote modem responds by displaying a menu and asking for a setup password. The MT3334HD8 has two default passwords. Please note that if you change them, you cannot retrieve them by resetting the modem by using AT&W1; you must know the new passwords to make any further changes. For further information on remote configuration, see Appendix F, “Remote Configuration.”

%%%AT<CR> Remote Configuration Escape Sequence

Enter the remote configuration escape sequence to initiate remote configuration when you are online with another Multi-Tech modem. The default escape sequence used by the MT3334HD8 is three percent signs (%%%) followed by the letters AT and ENTER. The remote configuration escape character, which is stored in register S13, can be changed either locally or remotely for greater security.

#Ixxxxxx Change Login Password

xxxxxx= password Default: #IMULTI-TECH

Use the #I command to enter or change the remote configuration login password.

AT#Ixxxxxx enters the current remote configuration login password, where xxxxxx represents the password. If the password is wrong, the remote modem responds with ERROR; if it is correct, the remote modem responds with OK, and you can proceed with the #S command.

AT#I=xxxxxx stores a new remote configuration login password, where xxxxxx represents the password. The password is case sensitive, and can be any combination of upper and lower case keyboard characters. It must be six to ten characters in length.
