> I need to know for sure if the Visor could sustain 115K communication speed. Is it possible at all? Typically serial communications over 9600baud require flow control. Generally at some speed point you run the risk of loosing data if you are not using hardware flow control. (and since Visors lack the necessary control lines to their UART I don't know if 115K is possible, I haven't tried.) I've worked only enough with the Visor serial port to know I won't support it. I'm unfamiliar with it potential capabilities. If it were a normal RS232 port or even a standard Palm device, 115K is no problem. I'd try is asking Handspring or reading their hardware SDK for serial port limitations. However, I've read Handspring is discontinuing the Visor line (I don't know the time table). IMHO If your developing new software and/or device, I'd think long and hard about putting resources into supporting the Visor line. If its for personal use, or a one-off thing for you company... happy hacking.
