RE: 48SX computer connectivity
First you need to acquire a hp48-serial to USB cable like the one here.

Then on the Mac running OSX ...

Download & Install MacPort (http://www.macports.org/install.php)

Run the "Terminal" application located in "Utilities" folder
// the following lines starting with "//" are comments
// on the command line, type de following ...

// update port software
sudo port selfupdate [return]

// update port installed packages
sudo port upgrade outdated [return]

// install kermit command line application
sudo port install kermit [return]

// connect the hp48-serial-to-USB cable & list your actives USB devices (in my case it's SLAB_USBtoUART)
ls /dev | grep USB [return]
// cu.SLAB_USBtoUART
// tty.SLAB_USBtoUART

// create a folder where you will put your HP-48 files
cd [return]
mkdir hp48 [return]
cd hp48 [return]

// start kermit software
kermit [return]

// configure kermit
C-Kermit> set line /dev/tty.SLAB_USBtoUART [return]
C-Kermit> set baud 9600 [return]
C-Kermit> set parity none [return]
C-Kermit> set flow-control none [return]
C-Kermit> set carrier-watch off [return]

> start kermit server
C-Kermit> server [return]

The HP-48S/SX Owner's Manual Vol. II Chapter 33 P.612 to P.634 explain how to configure and use the serial interface on the calculator.
