HyperTerminal
The HyperTerminal application can be used to upload firmware files into a Soundweb London device over the serial RS232 port if it is not possible to upload firmware over the Ethernet port.
HyperTerminal was included in earlier versions of Microsoft Windows. The last versions which included HyperTerminal were Windows XP and Windows 2000. It is no longer included with versions: Vista, 7, 8, 10, 11 but it can still be used in these versions.
The application can be launched in earlier versions of Windows from the location: Start/ All Programs/ Accessories/ Communications/ HyperTerminal
The files necessary for running HyperTerminal can be obtained from the Downloads section of this article. The Zip file contains two files: hypertrm.exe and hypertrm.dll. Extract these two files to the Desktop.
