No.  The KIO3B does not support FSK - you still need a separate FSK
signal connected to the ACC connector.

The KIO3B hardware (hub, FTDI UART, and PCM9203E CODEC) are essentially
identical to the microHAM USB Interface III.  However, the KIO3B lacks
an FSK output, does not have software that allows mapping the RTS/DTR
lines to a separate virtual ports (e.g. MMTTY with CAT on one port and
FSK/PTT on another) and it does not support tone based FSK (pFSK) or
CW (qCW) like USB Interface III.

With the KIO3B one needs a separate source of FSK and PTT independent
of the UART in the KIO3B.
