Hello! Let see if I understand you correctly: "txd, rxd, rts and cts lines to tck, tdi, tdo and tms" which is TXD goes to TDI RXD goes to TDO TCK goes to RTS TMS goes to CTS Which is interesting because I came across this page while waiting for your response: http://openschemes.com/2011/10/25/bit-bang-jtag-programming-of-xilinx-cpld-using-ft232-homebrew-svf-player/6/ That site discusses largely one or more of the ideas behind our program. And the picture shown comes largely close to your presentation. ----- Gregg C Levine gregg.drw...@gmail.com "This signature fought the Time Wars, time and again." ------------------------------------------------------------------------------ Everyone hates slow websites.
