aluRS232ControlLeadsState is an array of byte values used to indicate the current states of the input and output control leads. These state values are historically known as scan and drive values, respectively. These state values are the ones that get transported over the network (provided there is a means, such as HCM). As such, they are sometimes referred to as NETWORK-side values. For line-side values, see aluRS232ControlLeadsSignal. Each byte in the array represents the state of an individual control lead. The byte order is as follows: A byte value of 1 represents on (or high as per AluRS232ControlLead). A byte value of 2 represents off (or low as per AluRS232ControlLead). All other byte values are undefined. A particular byte is undefined if its config counterpart is undefined. For example, given an X.21 interface, aluRS232ControlLeadDsrDtr is undefined thus, aluRS232ControlLeadsState byte 'DtrDsr' is also undefined. Some bytes can represent something else depending on the interface type. For example, given an RS-530, RdlRi represents LlTm. See the respective object for details (eg. aluRS232ControlLeadRdlRi).
