Here is an alternative way to get a serial connector for your HP48SX:

1. Pay a visit to your friendly neighbourhood computer junk dealer
2. Walk up to the big pile of dead 5.25" floppy drives and find a
   drive with one or more 4-pin, 2-mm connectors (bring your HP or
   an 8-pin DIP IC; the HP should fit, the DIP should not)
4. Find the box with old, dirty D25 connectors and select one of the
   appropriate sex
5. Pay $2.50 for the dead floppy drive and get the D25 for free.

At least it worked for me.  Out of a dozen or so drives, at least two
had the right kind of connector.  They seem to be quite common in
floppy drives, to connect various kinds of sensors to the main circuit
board.
