Actually the 10in eee-pc and a more recent "9in with wider keyboard" seem to be quite okay, I read... :-) > I am particularly interested in using the netbook as a data > logger for an ascii text stream to the RS-232 serial com port.

If you log data in dos, it does not really matter whether it is text or binary, but it does matter that dos gives you all the cpu unless you ask dos to do work for you :-). I once used that for "real-time" data logging to RAM with a 32-bit (DJGPP compiled) C program. As nothing else uses much space, my program had many megabytes of space to pool data and then write it to harddisk in experiment pauses. In particular if you write to USB flash, either with BIOS help or with DOS drivers, you should expect some latency. > I assume that none of the netbooks would have a standard > com port so I was thinking that I could use a USB-serial > adapter to create a virtual com port. Does anyone know > if there are any available DOS drivers for these adapters? For PS/2 (keyboard, mouse) and now also for storage (flash but also floppy/harddisk) the BIOS will "be your driver". Only a few BIOSes support LPT or COM over USB, I believe. What you can do is use the dosusb driver by Georg Potthast which also has some "serial over USB" support. The COM-USB part is relatively new, so you could help testing it. The driver comes in two parts: The USB stack and a small driver which converts requests for a DOS character device into USB requests to the stack. You can also buy the source code if you want to fine-tune things yourself. The interface of the stack is documented, so you can write new drivers which use the USB stack as a black box which does the lowlevel work. Note that the DOSUSB stack does not support IRQ or callbacks yet, so the COM-USB module might be using (slower) polling.

PS: This is a "slim 25mm, high price" variant of the EEE PC, so maybe it is better to use a PC104 single board PC to save even more space. With the S101, you pay for XP, 10in display 1.6 GHz CPU, 16 GB SSD, 16 GB SD and 1 GB RAM... but you can already gather data in DOS each msec on a Pentium III or so. ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
