Day 745, Off, on, off, on

In, in, out, out - in, out, in, in.

For best results it would be ideal to be in rather than out.

In the case of the DE9 or DB9 subset of the RS232 standard the pins are configured like this:

1	Data Carrier Detect	in
2	Receive Data	in
3	Transmit Data	out
4	Data Terminal Ready	out
5	Signal Ground	-
6	Data Set Ready	in
7	Request to Send	out
8	Clear to Send	in
9	Ring Indicator	in

Interestingly the 'ins' outnumber the 'outs' by a ratio of 62.5:37.5

Surely it ought to be more equitable however you look at it.
