@@ +1 @@
+A simple USB emulated serial interface provides for control/readout of the TDC.
+The output is C5 code described in the IEEE paper, with encoding as given
+in Table I.  ''''Q0''' codes are sent continuously when the link is idle.
+Other codes may be sent by using the commands below.
+
+The input logic expects 8B/10B data in serial format at 25Mb/s.
+A ''''K.28.1''' code synchronizes the link and starts a transmission.
+Then 2048 words of 32 bits are received and stored in a block RAM for readout.
+
+The emulated serial port operates at 9600 baud, 1 stop bit, no parity
+and no handshaking.  When the board is powered up, after a 1s delay the message:
+
+{{{
+  TRM1.0
+  >
+
+}}}
+is sent and the board waits for text commands terminated by a CR or LF.
+All characters sent from the computer are echoed for convenience
+in operating with a terminal program.
+
+After any output from the command, a new ''>' prompt is sent.
+Commands are documented [https://docs.google.com/document/d/1IGZqD2rKQFlQ4Jv8SmbXRmuNURDFEiVixDCB6grOYzA/edit?usp=sharing here]
