WHO
Use the WHO command (Access Level 1) to obtain a list of devices
connected to the SEL-2032, including installed plug-in protocol cards. The
SEL-2032 responds with a table showing device type, protocol, baud rate, data
bits, stop bits, parity, and a device identification string for the device on each
port. The screen shown in Figure 8.34 is a sample response.

Figure 8.34 WHO Command
When a plug-in protocol card is installed, Port 17 or 18 will identify it. The
Parameters column indicates the capabilities of the card. The possible features
are:
FTx File transfer
VTm Virtual terminal
CTl Control operations
SBt SEL
BOOT
TIm Time synchronization
For each of these, there is an indication if the SEL-2032 can accept these
operations (H) and if the plug-in card can accept these operations (S).
/n Add a number “n” after an Archive data region reference to see that
record number within the archive record queue. Number 1 is the oldest
record, higher numbers reference newer records.
Example: VIEW 1:A3/4
NR n Add an NR followed by a count parameter “n” after a register reference
to see “n” registers of data.
Example: VIEW 1:0807h NR 4
Table 8.7 VIEW Command Parameters (Sheet 2 of 2)
Parameter Explanation
NOTE: You cannot use the clear
parameter C with /n, i.e., you can only
clear the oldest record.
