Looking for a cheap netbook with a serial port

usawrestling 347 118 February 21, 2011 at 12:04 PM
Hey all,

I am in the market for a netbook (or notebook, but would prefer a smaller size) with a serial port built-in (RS232). I am going to be running a very basic version of Linux on it, so it does not have to have decent specs.

I know usb-> RS232 adaptions exist, but they are extremely unreliable and I really need a built-in card.

I am open to other suggestions, such as the fit-pc2i (http://www.fit-pc.com/web/fit-pc2...c2-models/). If I can find a small computer, I can also add a monitor at a later date.

Looking to keep the price below $300, but could go a little higher if it fits my needs.

Thank you in advance for your help!

With the limited usefulness of serial ports to the mass market, I'm not sure how likely you are to find a netbook with a serial port. You're looking for a pretty specialized item, any newer laptop with one is probably going to be over your target price point, so you'll probably need to look for an older laptop.

I'd recommend IBM's certified used outlet to pick up an older Thinkpad. If you don't see any models with a serial port, check the compatible docks, they usually have a serial port. Thinkpads are also great for Linux. You could also look at eBay or Craigslist if you're comfortable with them.

Steve Gibson on password policies [grc.com]: I mean, I don't get this change it every eight weeks. ... It's not as if passwords are traveling by camel after they've been stolen, going to the bad guys, and so there's, like, some weird eight-week window, like, oh, we're going to change your password so that the stale password no longer works. ... And all this does is make IT people despised because users, who are not dumb, they think, why am I - why do I have to do this? What problem is this solving?

Thinkpads no longer have serial ports, either. However, you can get them on the docking station as Redmaxx suggested, or they also sell a serial/parallel adapter that fits into the media bay of certain models: http://www.amazon.com/Thinkpad-Se...B000F2HUWO

I think they were recommending older think pads. Nothing new has a serial port anymore at least in this formfactor. DIY motherboards do for pc.s

You aren't going to find a "netbook" with a serial port... four options besides USB serial adapter.

1. buy used. you might be able to get down to 12-13in size.

2. netbook with bluetooth (or a micro-sized bluetooth adapter) and a bluetooth serial adapter for the serial device, e.g. http://www.iogear.com/product/GBS301/ - have a friend that uses one of these to get "wireless" internet out in the boonies on their dialup.

3. buy a new full sized laptop. selection is somewhat limited, but dell has one with a serial port that starts at $500 http://www.dell.com/us/business/p...tude-e5510

4. if you don't need portability.. build a small form factor desktop.. e.g. mini/flex form factor with at least one expansion slot (x1 or pci) to add a serial port card if the motherboard doesn't have one (or at least the pin headers for one)

When you buy more, you save more. And when you save more, you can buy more.

nod I'm not quite sure at which point Lenovo completely eliminated the serial port. My T6x dock has a serial port. My coworker's W510 and its dock does not have a serial port.

they still put rs232 ports on laptops.... but it seems only the business lines. for example my wife's new Dell studio doesn't have any but the new laptop I just got @ work DOES have an rs232. Chances are slim of finding one on a netbook - kind of defeats the purpose of a small device.

The better Usb-to-Serial adapters with the PL2302 based chipset should meet your needs.
