Lines: 18 Does anyone know if there is a device that converts a hardware hand- shaking device into XON/XOFF protocol? Here's the situation. I have a piece of hardware that talks through RS-232. It only supports hardware handshaking (CTS/RTS flow control). I want to communicate with it with a NeXT computer. The STUPID !@#?^% NeXT serial port only supports software XON/XOFF flow control. So now I am looking for a device that translates a CTS transition from off to on, into a ^Q, and a CTS transition from on to off, into a ^S. So to simulate software XON/XOFF with hardware. On the same note, has anyone had trouble with XON/XOFF at speeds greater than 9600? Everything seems to work fine at 9600, but when I crank it up to 19200, something screws up and the buffers get overflowed. Robert Lin
