When sending only few bits of data via FTDI USB-Serial cable to the PC, you have to wait for one of the following conditions to occur before you get your data according to FTDI's AN232B-04, Data Latency Flow:
- The buffer is full
- One of the RS232 status lines has changed
- An event character had been enabled and was detected in the incoming data stream
- A timer integral to the chip has timed out.
I want to use option 3, enable an event character and also define it. How do I do that in Windows 7? I can't find any documentation on it. I don't want to have to write code to do it, I just want to know where in my operation system (Windows 7) I could change these settings.
