(Where r is the register number). Your modem returns: nn Where nn is the current setting of the register. OK You can view the contents of several registers with one command: AT Sr? Sr? Sr? Your modem returns: nn First register. nn Second register. nn Third register. OK Setting Registers: To change the contents of a register, in the command mode type: AT Sr=n ENTER Where r is the register number and n is the new value. Your modem returns: OK (dtc-07/30/93)
