 This might almost be a built-in...

 Node-Red is available for the R-Pi. There appear to be modules
available to create a web-page "dashboard". So... It should be possible to
define a "flow" for text inputs to a serial port and serial port to an
output (for any responses).

 I'm not familiar with Node-Red, and for some reason was unable to get
said dashboard to display an input item -- I did have a text input node
connected to a serial port (send/receive port node -- there are also
send-only and receive-only nodes).

 This would be simpler than a full-fledged web app and server
configuration, since the flows are defined by drag&drop nodes.
