ROOT CAUSE of 'connecting' hangs and intermittent port failures:
The DELTA-12G-e-h 8c is a bidirectional card. Without calling
VHD_SetBiDirCfg(board_index, VHD_BIDIR_80) before streaming, the
board remains in its default bi-dir config (likely 4RX/4TX) — so
RX stream opens fail with VHDERR_RESOURCEUNAVAILABLE on channels
configured as TX, causing random 'connecting' hangs per the SDK docs.
Per SDK Tools.cpp SetNbChannels() pattern:
1. Open temporary board handle
2. Check IS_BIDIR + channel counts
3. Call VHD_SetBiDirCfg(board_index, VHD_BIDIR_80) for 8ch bidir
4. Close temp handle, then open real board handle for streaming
Also add VHD_SetChannelProperty(VHD_CHANNEL_MODE_SDI) for ASI-type
channels per Sample_RX.cpp — required for 12G-ASI/3G-ASI channel
types to correctly detect incoming video standard.
