Check you system or get the 1.3.2 serial.device. An A500 without any true fast ram can do CTS/RTS @ 19.2kbps without data loss. Your milage may vary depending on what other things you run and have attached to it though. XON/XOFF handshake is a different matter at high rates though, it always drops a few characters. -jack-
