You probably won't easily get away w/o some kind of driver or configuration in windows.... Also you might consider USB for your concept. Check out: http://www.beyondlogic.org/usbnutshell/usb7.htm#PIC16F876Example --Also, you have seen the usb memory fobs from IBM / DELL (16MB + in a device that fits onto a keyring)? They're getting pretty inexpensive. ----- Original Message ----- From: Joris van den Heuvel Does anyone have any experience in using a PIC as a serial remote connection device in Windows 9x? I have this idea of a "removable non-volatile RAM module" hooked up to a PIC and being able to access it as a network drive in Windows 9x through a COMport. I know it's possible to connect 2 PCs this way, but would an 'F877 be able to support the protocol? And of course, what protocol would this be? Even better would be someone who's done this sharing his thoughts. The reason is this: I'm trying to work within standard Windows capabilities so I don't have to write my own Windows9x software and support it. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
