It is straight-thru.
Please note that if you are connecting from a 9-pin male PC port to
the HB interface's 25-pin female, the means that you have the
following mapping:
DB-9 DB-25
2 3
3 2
5 7
In other words, the same cable as you would use to connect to a
standard 25-pin female modem.

| The "modem cable" used to connect the computer to the serial interface/charger: Is this a "null modem" cable with the transmit & receive lines (pins 2 & 3) crossed, or is is a straight pin-to-pin serial cable?
