Your academic perspective is appreciated, and it is true that in the professional world, especially in the retail sector, compatibility with specific peripherals is crucial for the smooth operation of operations. > From a position of ignorance, I would have thought that serial > pass-through printing is necessarily bidirectional, if only for > flow-control, but UARTs can do that in hardware with RTS/CTS. > So it's unlikely that that's enough to support what the OP wants, > which is probably things like ink/paper supply or, when there's > a cash drawer installed, drawer open/closed; typical POS stuff. > And that's without taking into account the peripherals mentioned > above. Regarding the use of Putty, it appears that in some cases, it can partially meet our needs by allowing interactions such as printing tickets and opening the cash drawer. However, i also mentioned that some other operations do not work. It is important to note that Putty is primarily designed as a terminal emulator and may not be equipped to meet all the specific requirements of our retail application. As for the evolution of Putty, it is understandable that the developer has not responded to our contact attempts, and we respect their decision to maintain the software according to their own criteria. I also pointed out that we have proprietary emulator solutions that come with integrated hardware offerings, such as Wyse-type client terminals or Android tablets. These solutions meet our needs and provide the necessary services at a given cost. I just to emphasize that the diversity of options, whether open source or proprietary, is a wealth, as it allows each company to find the solution that best suits its needs. Ultimately, our goal is to find the best solution for our retail application, taking into account hardware compatibility, required features, and associated costs. While we are open to exploring open-source solutions if they can meet our needs, we also value the reliability and support that proprietary solutions can provide. We will continue to evaluate all available options, ensuring that we choose the approach that best aligns with our business requirements and technical considerations. Regards, Thierry
