WinSSD Ports Utility
The WinSSD Ports utility allows the user to select the COM: port number, set data rate, data bits, parity, stop bits and flow control.

WinSSD's Loopback Test allows functional testing of any serial port on the system, provided a loopback plug is present. WinSSD provides a pattern test, an ASCII test, and a modem control signal test. Multiple passes can be programmed to meet the user's requirements. Loopback plug diagrams are provided to aid in building loopback plugs.
Multithreaded bit error rate test application for verifying serial port performance. WinSSD's BERT test can be used in loopback or point-to-point test configuration. This software tracks bit errors and sync losses while displaying transmit and receive frame counts, the number of bytes verified, and driver error statistics.
