Hello. I have the task of building an interface between an old serial device with limited and obscure flow control and the serial port on a PC. Programs on the PC fail, because the device is expecting real time synchronous communication, which Windows is having a hard time doing. My idea is to build/program an interface box that sends information through a serial port to a device and captures the data coming back into RAM. When the device is finished, I can then download the information in the RAM to a PC through another serial port on this device which. This part will then not need to be time dependant. My question is, where do I go to get started and what types of things are available where I could program a chip to do something like this? Thank you in advance!
