I have an vista notebook without a hardware rs232; i tried to upload via a profilic 2303 usb-rs232 adapter without luck; so I checked for many hours the forum to find a solution. at my win98 PC the compilation fails with v11 and v14, but this one has a rs232.
the serial communication with the board is proofed with a simple programm made with bascom-avr, in both directions, to a terminalprogramm.
I have found out, that in the v09 an older gcc ist used, with should do the job with win98.
I ask in this topic because there is a big change with the server migration I think: the older versions are no more available.
maybe tomorrow.
thanks for first answer, andi
