#LEGACYMODE – Legacy Mode Enable/Disable
About Legacy Mode:
Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP)
Legacy mode allows for smoother transition to TCP/IP based connectivity from standard analog
interface connections.
When #LEGACYMODE=1, the stack will be in pseudo legacy mode where the commands &S,
&D, &C, A, D, S0, E, V operate independently of the stack. The commands will be saved to a
different NVRAM location and will not affect the IP stack once legacy mode has been exited.
Once in legacy mode, the user can configure the #TCP values and issue an ATD command to
make a connection to the remote host. If necessary, the user can also issue
ATDxxxxxxxxxxxxppppp where x is the decimal address and ppppp is the remote port. The stack
will perform the physical connection and present the user with the proper messages:
NO CARRIER
