to the command state after it processes the portion of the dial string preceding the ";". This
allows the user to issue additional AT commands while remaining off-hook. The additional
AT commands may be placed in the original command line following the ";" and/or may be
entered on subsequent command lines. The modem will enter call progress only after an
additional dial command is issued without the ";" terminator. Use "H" to abort the dial in
progress, and go back on-hook.
