Cheap wireless between desktop PC in basement and RS232 device upstairs?
-RS232 serial port on which is sends and receives data periodically.
PC in basement has:
-RS232 serial port
-and is connected to home WiFi Router
The device and pc communicate at 115200 bps, currently via a long serial cable...which i'm trying to get rid of.
Basically i need a wireless rs232 link (between serial port of the device, and serial port of the PC)
some sort of hybrid link (between serial port of device, and PC ..via wifi or bluetooth)
Cheapest solution i know so far, costing less than $30-$35, is for a hybrid scenario:
-buying a used and cheap Linksys WiFi Router WRT54G from Ebay,
-hacking it to add changed firmware (it's Linux open source),
-adding serial port to it ..this basically turns it into a Linux PC with built in Wifi and Serial Port.
-write custom Linux program that runs on the Linksys router that sends the serial data to my PC...
Might be cheap solution but very scary to me, because i'm only used to writing code for Win32 PC platform. I know next to nothing about Linux !
Any other ideas?
