After I update to OS X 10.11.2, El-Capitan, from 10.11, my Aten USB to Serial UC 232A no longer works properly.
When I send hexadecimal data, for example client send :
02 01 10 30 30 30 03 CB, the server will receive
02 01 10 FF 82 8A 03 CB 00. Server always receive different data even when I send same data twice. Somebody can help me? Thanks.
- I use MacBook Pro - Mid 2014
- I use CoolTerm to send data and the Adaptor is Aten USB to Serial UC 232A.
