Use our Modem Splitter to connect three terminals to one modem and save money - you won't need extra modems and extra lines!

The Modem Splitter is transparent to speed and protocol and works equally well in sync and async environments.
The TL073A-R4 includes (1) modem splitter, (1) 6-ft. DB25 male/DB25 female extension cable, and (1) serial DB9 female/DB25 male AT adapter.
