The DB25 male and female is a standard connector for RS232 serial. However, IBM decided to deviate from that standard and used it differently. On the PC, a DB25 female is the parallel printer port, and the DB25 male is a COM port (serial). The COM ports also come n a DB9 variety that was introduced with the IBM AT computer. Use of a DB25 for SCSI can also be found, but it is an oddity - not really a standard. HP uses it for some SCSI scanners, and Apple used it as well.

Does anyone know the sex on the connector on the PC side of the connector.
