![]() ![]() This type of software is capable of emulating all serial port functionality, including Baud rate, data bits, parity bits, stop bits, etc. Detection and handling of network interruptions, possibly with an automatic attempt to reconnect to the device server to resume application data flow.Management of the IP routing table to avoid loss of an IP route to the device server.Network connections through proxy servers.network packetization and Nagle's algorithm. The timing effects of the TCP protocol stack, e.g. ![]() ![]() Data rate limiting of the application data stream to provide the performance expected for the baud rate currently in effect on the virtual COM port, which is slower than the maximum speed of the network connection to the server.(This is not the same as hardware/software flow control of the serial device itself.) Flow control of the network data stream to prevent overrun of the server.Accepting inbound connections initiated by device servers running in client mode and routing the data stream to a waiting application.Initiating the network connection to a device server and determining that server is ready to relay application data.Device servers for certain applications, such as those that use wireless networks, use UDP instead of TCP to gain performance at the risk of network reliability. Several of the larger server manufacturers use proprietary protocols in addition to, or instead of, public protocols. The majority of server manufacturers use public TCP protocols (raw, Telnet, or Telnet with RFC 2217 extensions). Most device servers are accessed with TCP connections (raw or using the Telnet protocol) to gain reliable delivery of the application's data stream in order of transmission. Network protocol support that is compatible with the device server.Redirectors address a number of issues related to the network connection, including: ![]()
