Modem sharing device for sharing serial connections
From Wikipedia, the free encyclopedia
A modem sharing device,[1] also called a line sharing device, modem sharer or line sharer, allows multiple Binary Synchronous Communications devices to share a serial connection. Synchronous and asynchronous datastreams are supported. A common example was a Tandem host connected to automatic teller machines, with a modem or router in between.
