Therefore hardware flow control (RTS/CTS) won't work. If you have a
vintage device, it might need hardware flow control or other signals
in RS-232 for it to function properly and these devices won't handle
that.
I had to compensate for the outbound version of this with a serial print
buffer set to use software flow control.
never had a problem with the inbound to the device problem since none of
them handled software flow control anyway. They all worked with human
type input, and the output worked fine with the print buffer.
Input == from network / attached device to a serial port on a system.
output == data from a serial port to a network adapter or attached
buffer device.
It was easier to buy a cheap serial buffer than to write code to try to
compensate for it in the devices I was attaching.
