; Experimental minimal CONNScanInfo call through Client32/NIOS.
; It resolves CONNScanInfo and calls NIOS command 0x0A with:
; - no scan criterion
; - no returnConnInfo
; - a 4-byte iterator/connRef buffer
;
; This follows the d32wrap.o _CONNScanInfo call mechanics, but avoids the
; higher-level NWCString/SPECTDATA conversions for the first probe.
