!ENn Enable Data DN/MSN n

Unit: Decimal ASCII code

Values: n=1 (enable Data DN/MSN 1),

n=2 (enable Data DN/MSN 2)

Default: All ports are enabled

!ENn enables a Data DN/MSN which will put it back in service for accepting and originating

data calls. If no port number is given then the assumed port number is that of the port from

which the command was received. AT!L<CR> may be used to review which ports are enabled

(any port that does not display PORT DISABLED). The @CONFIG configuration menu can

also be used to enable or review the disabled ports.
