USB Serial Adapters by Quatech

Quatech USB Single Serial Port Adapters are easily configured to enable the continued use of legacy devices without making any changes to the applications written for them. The adapters enumerate themselves as standard COM ports making the USB interface completely transparent to software.

Quatech’s USB Single Port Serial Adapters are based on the idea that taking advantage of new technology should not necessitate abandoning legacy devices and the applications written for them.
