I want to use an FT245 with a terminal program only, assuming that the terminal can send all characters (0x00 to 0xff) can this be done? If so what are the commands available.
I only need to set/reset the 8 data lines.
Thanks,
Maxwell

Hello Maxwell,
The VCP or D2XX drivers can be used to control the IC:
However note the data transfer rates:
- up to 1 Megabyte / second with the D2XX Direct Drivers.
- up to 300 kilobyte / second with the VCP Drivers.
Please see the FT245R Datasheet (https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT245R.pdf) for more information.
TN_167 FTDI FIFO Basics (https://www.ftdichip.com/Support/Documents/TechnicalNotes/TN_167_FIFO_Basics.pdf) also provides useful information.
So if you are using the VCP port via a terminal, simple read and writes are possible.
Note the FT245R is a FIFO slave which is controlled by a master.
You can test and evaluate using our UM245R (https://www.ftdichip.com/Products/Modules/DevelopmentModules.htm#UM245R).

I have trawled the data sheets and can find no information regarding simple control/setup via the VCP port and a simple terminal programme. Please point me in the right direction. I am (and have) using FTDI serial devices on many projects, these work "out of the box" very well. All I need is the byte sequence to setup the 245 for simple on/off control of the output byte. Various "relay board demonstration" programmes work but I am stuck with a serial port only (it was hard enough to get the management to accept a VCP for the other ports). Sending bytes to the 245 after running a demo relay program works, not if I simply send the data after a cold reset.

Was there a solution for this problem?

Please share the solution
I also need to control my interface (FT220) using VCP
But I can't find any example of the messages to configure the interface and I/O signals, then communicate with the remote device
Please share an example
