Damned that makes things more complicated :) That could push us along the following lines ? CONSOLE_DEVICES = "/dev/ttyS2 /dev/tty1" CONSOLE_BAUD_ttyS2 = "1500000" CONSOLE_BAUD_tty1 = "115200" (well, with /dev/ being what it is, CONSOLE_DEVICES = "ttyS2 tty1" could even be decided as sufficient, removing any possibility for syntactic ambiguities) or maybe even this ? CONSOLE_BAUD = <default value> CONSOLE_BAUD[/dev/ttyS2] = <overriden value>
