English Asynchronous and Synchronous Communication
The Hostess range of multiport serial controllers includes both intelligent and non-intelligent synchronous and asynchronous products designed to meet your needs. Widely used by many major OEMs and System Integrators, they are simple to install and easy to use.
Hostess and Hostess 550
These were the first multiport controllers for the PC and are still in use today in a wide range of systems. They provide a low cost asynchronous solution using non-intelligent controllers.
Features include
|  |
Hostess i
The Hostess i range of intelligent controllers enables you to download code to the controller to reduce the load on the computer's CPU. Available soon in PCI format.
Features include
|  |
Hostess i/S2
This synchronous two port intelligent controller has the same powerful features as the Hostess i series and is ideal for off loading system overhead by running synchronous protocols on the controller.
Features include
|  |
Hostess SV24+
For low cost synchronous communications the Hostess SV24+ is an economical 2 port non-intelligent controller that can operate at speeds of up to 1.28 Mpbs and supports both full and half duplex data transfer modes.
Features include
|  |
Smart Hostess
The Smart Hostess can provide 4 or 8 ports that can operate either synchronously or asynchronously giving considerable flexibility. Programs can be downloaded to the board to reduce CPU load.
Features include
