you may want to try the following :

tfh% ll /dev/pas*
crw-------  1 root  operator   31,   0 Jan 16 17:50 /dev/pass0
crw-rw----  1 root  saned      31,   1 Jan 16 17:50 /dev/pass1
crw-------  1 root  operator   31,   2 Jan 16 17:50 /dev/pass2
crw-------  1 root  operator   31,   3 Jan 16 17:50 /dev/pass3
tfh%
