Programming Port

[Greg Ross]

Near the end of the documentation pages for the DEBUG command, it states:

DEBUG is actually a special case of the SEROUT instruction. It is set for inverted (RS-232-compatible) serial output through the programming connector (the SOUT pin) at 9600 baud, no parity, 8 data bits, and 1 stop bit. For example,

DEBUG "Hello"

is exactly like:

SEROUT 16, $4054, ["Hello"] ' like DEBUG for BS2

in terms of function (on a BS2). The DEBUG line actually takes less program space, and is obviously easier to type.

That given, the only reason I can think of to use SEROUT instead of DEBUG, would be to use a higher baud rate than 9600 -- an interesting idea, though I am not sure how valuable that would be.... BUT to answer the original question, the pin is 16
