Today, I try to use my colleage's usb to com cable, to connect SPARC machine. 1. check /dev/term folder first. # ls -al /dev/term total 8 drwxr-xr-x 2 root root 2 2009-11-10 18:20 . drwxr-xr-x 252 root sys 252 2009-11-10 18:20 .. 2. connect cable then try again. # ls -al /dev/term total 9 drwxr-xr-x 3 root root 3 2009-11-10 18:00 . drwxr-xr-x 253 root sys 253 2009-11-10 18:00 .. lrwxrwxrwx 1 root root 48 2009-11-10 18:00 0 -> ../../devices/pci@0,0/pci1043,8263@1d/device@1:0 3. use tip command to connect SPRAC machine. PS. you have to set baud rate to 9600. # tip -9600 /dev/term/0 4. Start the SPARC machine then you will get the console. Wish this helps. regards, Stanley Huang
