IC (Misc. Icons and Status; GET only)
RSP format: ICabcde; where abcde are 8-bit ASCII characters (Byte in Table 4 below) used as collections of
flags (Bit in table). Each flag represents the status of an LCD icon and/or a specific transceiver function.
Some functions whose status is indicated by IC command flags can be controlled using other commands. For
example, the K3 can be put into TX TEST by sending SWH18. The condition can be verified at any time using the
IC command (byte a, bit 5). Another example: ESSB (extended SSB) can be turned on/off using an MN (menu)
command, followed by SWT11, simulating a tap of 1 on the keypad. Again, IC can be used to verify the present
state (byte d, bit 5).
The 8
th bit (B7) of each byte is always 1 to ensure that control characters are not sent to the computer. The other
bits are defined as shown in Table 4.
Table 4 IC response fields. See notes below.

* These bits are reserved for future use.
** If BSET is in effect (byte a, bit 6=1), the values of some other flags may change or may be invalid. The
application should examine this bit first.
§ Per-mode, or per mode-group (e.g., MSG bank # is stored separately for CW/FSK-D/PSK-D and voice/DATA-
A/AFSK-A).
