Controlling serial link parameters via NVT

June 1, 2011

From version 4.1.5

NVT (Network Virtual Terminal) is defined as a part of the Telnet protocol. It contains a set of commands that can also be used to transmit commands and settings to a remote device. From the Telnet protocol functions defined in the RFC 2217 standard, Reliance 4 only uses the functions related to setting the serial interface parameters. In this way it will be possible, even at runtime, to change the communication speed or parity of the connected Ethernet/RS232 converter (RS485, MBUS). The communication driver can make these changes automatically, by sending a special NVT control command via Ethernet. The condition is to use the converter that supports changing parameters via NVT.
