Note: From the user point of view, using HW VSP in service mode has many advantages. Furthermore, since service administration requires administrator privileges, securing a VSP against misuse is as simple as not installing the client-side part. However, in order to improve stability, only one user may access the service and change virtual port parameters at a time. Parameters of a VSP running on a remote server can be easily changed from a local PC. Support for Windows 2008 Server is being tested.) In this mode, HW VSP consists of a client-side part (setup GUI) and a server-side part (the service itself). (At this time, HW VSP fully supports Windows 2000 Server and Windows 2003 Server. Running HW VSP as a standalone application requires starting it under a logged-in user and therefore prevents autonomous operation on Windows servers. Running as a NT service / in client-server modeĪbility to run as a service has been the main reason for developing the new version. When using HW VSP together with recommended devices produced by HW group, it is possible to change connection speed, parity, and other communication parameters (as well as to control any digital outputs and inputs) remotely on the fly via the RFC-2217 protocol, thus achieving a true remote serial port behavior. Therefore, the scenario very closely resembles behavior of a real serial port. Upon receiving RS-232 data, the converter establishes a connection with the PC and passes the data to the virtual COM port. involving GPRS devices), the PC with the HW VSP driver can be set to operate in TCP Server mode, enabling the remote device to initialize the connection by sending any data to the remote port. HW Virtual Serial Driver is intended primarily for devices produced by HW group, although it can be used for free as a universal driver that creates a virtual remote serial port, which redirects data to a predefined TCP/IP address and port. Baudrate emulation - when no flow control is available.VSP in TCP server mode uses 0.0.0.0 as a pre-entered IP address.In the service mode, both versions run as a client/server application allowing you to create, reconfigure and remove virtual ports remotely using a client-side part of VSP – useful for multi-port applications.Receive buffer cleared when a port is opened.Automatically connects to a previously opened serial port.Configuration is stored in an INI file for easy backup or transfer to another PC.Supports all 32-bit or 64-bit Windows systems, including Server versions.Complete support for Windows 8 and Windows 10.Runs as a stand-alone application, or as a NT service suitable for servers.Multi-port version is available only for HW group products.Single-port version of HW VSP3 is available freely.
