11 -channel, -chn
12    reports per channel status information for each device. The
13    channel is displayed following the device name.
14 -cylinders, -cyl

17 -detailed_status, -dtst
18    displays detailed status if available.
19 -device STRs, -dv STRs
20    reports information for the device(s) named, where STRs are device
21    types ("prt") or device names ("prtb").
22

24 -for T
25    computes the ending time from the starting time, where T is a
26    relative time (such as "1 hour").
27 -from DT, -fm DT
28    starts scanning the log at the date/time given.
29 -hex_detailed_status, -hxdtst
30    displays detailed status in hexidecimal if available.
31 -io_command, -ioc

51 Notes:  If -from DT is not specified, the scan starts with the earliest
52 message in the syserr log.  The ending time can be specified by using
53 -for, or -to, but not both.  If both are omitted, the scan terminates
54 with the last message in the log.  All dates and times must be in a
55 format acceptable to convert_date_to_binary_ described in the Multics
56 Subroutines and I/O Modules manual, Order No.  AG93).
