Hi!
Can anyone give me a suggestion about the following problem?
I need to store data on an external disk via a file-based interface (open_file, getch(), putch(), etc.).
I was thinking about a using Flash-disk, but the only HW-interface I've got is a RS-232 port.
So, I'm looking for a flash-disk with an RS232-interface on which 'normal' file-based functions can be executed.
Thanks for your suggestions!

If this is your product, then you can perhaps make your own. A low-cost AVR could act as a protocol converter, turning "UART" into SPI, MMC, CF, or whatever.

Maybe you can use a USB to Serial converter IC together with a USB Flash Disk ? Speed might be a problem. Bit toggled SPI might be faster to something like Atmels dataflash ICs.

A USB to serial converter are slave devices only. PC being master.
An USB master device for embedded systems is still unavilable.

You might be interested in TERN's FlashCore-B product:
CF-interface, 2 RS-232 ports, and a FAT12/16 filesystem, for $99 qnty.
It's C/C++ programmable, but a serial-only interface is also available if you want to stay away from programming the board (although we strongly suggest that you give it a try and take advantage of the flexibility).
