USB to RS-232 converter with 5 Baud
-
Does anyone know a converter with this capability. I am looking for a USB to serial converter or chip (like FTDI, Prolific, Microchip) that is capable of doing 5 Baud. thanks

Why are you trying to go that slow? ...you can simply oversample a slow incoming signal btw (turn it into a high rate signal), but you have to make sure you have DC coupling wherever the slow signal is coming into, not sure if USB is AC or DC coupled. If it happens to be AC coupled, the slow DC rates are going to get filtered out by the coupling capacitor.

Hi Kiran, I ran into the same problem some time back, a communication link had a 5-baud initialization sequence where communication parameters were negotiated. Unfortunately we did not find any UART that supported this reliably. So our solution was to use a GPIO pin combined with a UART, implement the 5-baud initialization by sampling the GPIO input and after the negotiation switched the GPIO to high-Z and enabled the UART, now with a supported, high baud rate. Hope this helps.
