All,
I built a webserver for a rs-232 connected weatherstation from 1998 era laptop. (256 MB ram, low power CPU)
I only used the screen / keyboard early on to configure things. Also the laptop never moves so there is no advantage to it being a laptop. The laptop has died so I want to replace it.
I'd like the replacement to be relatively small so it can fit under a bed, etc.
I've got a keyboard / mouse / monitor I can hook up for the initial build, but I would hope after that all support would be via ssh. I'd like the PC to have a rs-232 connection just because I've read the weatherstation doesn't work well with usb-to-rs232 adapters.
Recommendations?
In your searches, you might include the term UART (Universal Asynchronious Receiver Transmitter), as this is the circuit which is used to make an RS-232 interface.
Maybe an ARM based platform (one supported by openSUSE).
Thanks Greg
-----Original Message----- Hi Dirk, I think the general phrase "serial port" might be more appropriate than UART. When refering to uart, people mostly think about the chip, while the functionality last couple of years has be incorporated into the south-bridge. ARM based devices might be better in some aspects (power, price, size) but most of them don't have a serial port or lack mem/cpu-power to do something useful <<<<<<< as a general purpose replacement pc. To avoid flames, for some single purpose projects ARM-boxes are ideal. hans. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
