When the interface receives a preciously memorised code it sends the following sequence of
characters to the PC via USB:
R/X1-X2X3X4X5X6X7X8X9X10-X11.
Where X1 represents the transmitted channel (A,B,C or D), X2-X10 the transmitted code, while
X11 can either be equal to E if the interface is enabled or D if it is disabled.
If the characters &IC are sent the interface answers with a sequence of characters that rep-
resents the actual settings.
Note 1:
The first bit to be transmitted in the output sequence is bit 1
