Ladies and Gentlemen,
Earlier today, I had to dial into a server to check a link from both
sides (a router was down). This evening, when I connected to the
server I am not able to connect to the modem.
From dmesg
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
uart0: [FILTER]
Using cu -l /dev/ttyu0 I receive a message stating "link down".
I have issued a kill -HUP 1 to restart the ttys and receive the same
message. The same thing happens when rebooting the server.
Trying to open the port with minicom, I receive the following message
minicom: cannot open /dev/cuau0: Operation not permitted
If I change the port to /dev/ttyu0, I receive the following message
minicom: cannot open /dev/ttyu0: Permission denied
Permissions on /dev/ttyu0 and /dev/cuau0 are as follows
crw------- 1 root wheel 0, 41 Apr 5 20:03 /dev/ttyu0
crw-rw---- 1 uucp dialer 0, 44 Apr 5 20:03 /dev/cuau0
Is this a hardware issue or am I missing something else?
Thanks,
Jay
