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
-connected to home WiFi Router
The device and pc communicate at 115bps ... currently via a long serial cable.
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 about $40, is for a hybrid scenario: buying a used and cheap Linksys WiFi Router WRT54G, hacking it to add changed firmware (it's Linux open source), adding serial port to it and connect my device to it + write custom 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?
