# cmd modbusadd

cmd modbusadd 5 Serial A

When the modem is upgraded to firmware version R1.2.1 and has been previously set to cmd mode 6,

modem configurations containing the form modbusadd id n p d s m w will automatically be converted

upon power cycle to modbusadd id Serial m and port n d p s f (where f = 2 if w = f or F, and f = 0 in all

other cases).

After upgrading to firmware version R1.2.1, to convert from modbusadd id n p d s m w to modbusadd id

Serial m when another mode has been previously configured, enter cmd mode 6, cmd save, and power

cycle. To restore the modem to its previous mode, enter cmd mode n (where n is the previous mode),

cmd save, and power cycle.
