I don't think we should care much about OpenCT support of an SCardControl() equivalent. OpenCT use is strongly deprecated. I do not expect to see a PACE reader supporting OpenCT but not PC/SC. A void or empty control() function for OpenCT would be fine with me. The idea is to have the code to compile with OpenCT but in a degraded mode.
