Hello, I've got a network box. The motherboard (adlink 2000) has three "com" ports (that is what the screen print on the board says: com1, com2, com3.
The box I was given for development has com1 wired up to the 9pin port on the back of the housing, helpfully screen printed with 'COM1'. com2 is wired to a Densan 16x2 LCD front panel display. Development happened. Comes time for testing, and it turns out that the box I have is "miswired" vis-a-vis the sio ports. Every other box by this manufacturer is wired com1 -> LCD, com2 -> COM1. My kernel configuration had this: a) device sio0 at isa? port IO_COM1 flags 0x10 irq 4 a) device sio1 at isa? port IO_COM2 irq 3 a) device sio2 at isa? disable port IO_COM3 irq 5 a) device sio3 at isa? disable port IO_COM4 irq 9 So now I'm trying to swap the ports at the kernel level so that the LCD control characters and data which went to the mb port com2 (sio1) go to com2 (sio0), and the console output moves from com1 (sio0) to com1 (sio1). I've tried b) device sio0 at isa? port IO_COM2 irq 3 b) device sio1 at isa? port IO_COM1 flags 0x10 irq 4 b) device sio2 at isa? port IO_COM3 irq 5 b) device sio3 at isa? disable port IO_COM4 irq 9 and c) device sio0 at isa? port IO_COM2 irq 3 c) device sio1 at isa? port IO_COM1 flags 0x30 irq 4 c) device sio2 at isa? port IO_COM3 irq 5 c) device sio3 at isa? disable port IO_COM4 irq 9 The b) lines resulted in no console output (bad), but serial login on the 9pin COM1 housing port (good) but no LCD output (bad) the c) lines resulted in no console output, no serial login on COM1, and no LCD output (bad, bad, bad). Is this going to require more changes, elsewhere? And shouldn't the b (or c) lines do what I want (console output, serial login and LCD output)? Help?
