Re: [Flashforth-devel] Xon/Xoff how to

[Mikael N. <mik...@pp...>]

I agree, with USB the best solution is to use HW flow control.
I am using now a Microstick2 on a Microstickplus peripheral board.

The Microstickplus has a MCP2200 USB serial bridge.
The CTS/RTS pins are not connected from the MCP2200, so some soldering
is required to connect the CTS (SOIC PIN13) to a free PIC pin.
I connected it to the RB12 led pin so I get a nice flashing led each 
time the CTS line is asserted from FlashForth.

The MCP2200 configuration utility (Windows) must be used to enable 
CTS/RTS pins. These are not enabled by default on the Microstickplus board.

Works a 100 % reliable without any delays configured in minicom.
