![]() ![]() The configured and runnig incoming transport opens port of serial interface for the expectation of the requests of the clients. If necessary, Organization of a local serial line with a pair of connected ports is recommended to use the command " $ socat -d -d pty,raw,echo=0,perm=0666 pty,raw,echo=0,perm=0666". Global blocking of the serial device is not carried out in mind the ambiguity of this process at the system level, and re-use can lead to unexpected problems. In normal mode, the serial interface is not allowed to reuse one and the same port incoming and outgoing traffic. That is the input transport will ignore all requests while the output transport's established connection allow, in idem time the output transport will not try make connection while the input transport have connection or other an output transport connected to other telephone, for example. Misc mode mean an input transport allow, which wait ingoing connections, and also an output transport allow at idem device. Into modem mode by the module support misc work mode. To add new incoming and outgoing interfaces is possible by means of configuration of the transport subsystem in the system configurator of OpenSCADA. Incoming and outgoing transports are supported. Module of transport Serial provides support of transports based on the type of serial interfaces RS232, RS485, GSM, and others to the system.
