I'm using my Thinkpad 770X as the GDB host and it says: sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A On the machine I'm trying to debug, a Dell Precision 410, I have: sio1 at port 0x2f8-0x2ff irq 3 on isa0 sio1: type 16550A I suppose I could rip open the case to try and find what part they put on the motherboard for the 16550 support, but I'm had similar results with other machines. In GDB, you see some message about "malformed messages" and you can't seem to do anything. The other odd part is that speeds up to even 115200 work just fine up until the point that interrupt services are enabled. Then your hosed. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
