The function sets the TTL Port value.
For protection, by default all channels are disabled after power-up and reset. The channels can be enabled and or disabled by calling Gx5641SetChannelOutputState.
Note: The channel should be set to Static I/O mode prior calling this function by calling Gx5641SetChannelMode otherwise the function returns an error.
The following example sets channel 0 TTL Port value to 1:
Gx5641SetChannelTTLPort (nHandle, 0, 1, &nStatus);
