XModem Library for the HP-48

The XModem Library is an XModem Server for the HP-48.  On the HP-49 this capability is built-in.

XModem is a faster protocol than the built-in Kermit Server of the HP-48.

 

Built-in HP-48 XRECV Command
The HP-48 has a built-in XRECV command which can be used with Debug4x's Download Project (Manual-XRECV) Menu.  This leaves the details of installing the project to the user.  This usually involves a tiresome number of keys and operations on the calculator.  Using the XModem Server Library these operations can be done automatically just as the Autoload capability does with the EMU48 emulator for the project.

 

Installing the Library
To install the library, first connect the HP-48 to the PC with a cable.  Then download the XSrvr library by:

Once the download is complete, retrieve the library from the variable by typing VAR X (or whatever variable name you used for the download).  This places the library on the stack.

Now store the library in port 0 or 1 by typing 0 (or 1) STO.

To attach the library, turn the calculator off then ON.  The library will attach itself to the home directory.  Press right-shift LIBRARY and press the XSRVR menu button to obtain the XSRVR menu.
