      @oe1cxw Do you know the default frequency for the cable. AFAICT, 0 is a valid value for frequency (static struct init)!

      @oe1cxw I am asking ONLY because this is the first time I've ever done CPLD programming successfully. Idk if it's supposed to be this slow.

      @cr1901 can you make an example SVF or XSVF file (whatever you are using) for me to look at? What CPLD are you programming?

      @oe1cxw Sure, this is the breakout board I bought: http://dangerousprototypes.com/docs/XC9500XL_CPLD_breakout_board … and here are the dev files: …https://dangerous-prototypes-open-hardware.googlecode.com/files/CPLDdev.package.v1.1.zip … >>

      @oe1cxw I used the files named "Tutorials/xc9572xl/Verilog-CPLDIntro*.svf to program the board. All took 10-13 minutes! On Windows, FWIW.

      @cr1901 I think this is a windows related problem. On Linux (wo/ CPLD, ignoring TDO errors) it takes about 5 seconds. 3.8 sec w/ FREQ 2e6 HZ

      @oe1cxw Just out of curiosity, you're sending one command at a time per call to libftdi and not saving them in a bulk buffer?

      @cr1901 It buffers up to 16 kbits (BUFFER_SIZE) and then writes command(s) + data in a single ftdi_write_data() call.
