Simple Sinclair QL Network File Server (C) Jason Lucas 2019 This is a work in progress. It may contain bugs. Use with caution. Provides an inexpensive way of transferring data to and from a QL using the QL network interface. The source code can be simply compiled using the Arduino IDE. Notes: Only one file can be opened at once. Executable files will need a 15 byte file header added to the start of the file Some versions of Toolkit 2 have a bug in the LOAD command, incorrectly requiring BASIC programs to have a file header - A fix for this has been provided an can be activated/deactivate by setting the useTK2Fix variable in the source code (default: true) In some combinations of Toolkit 2 and Minerva ROM, networking does not work correctly - either update your ROMS to the latest version, or either disable TK2 or Minerva. Commands: There are two versions of the commands code - one just as SuperBASIC procedures (net) and one compiled as a QLiberator extension (net_obj). To use the latter, you will need a copy of the QLiberator runtime (QLib_run) An example boot file is included to load the QLib extension version of the commands NFILE "filename" - sets the currently active SD file NDIR - view the current SD directory NDEL "filename" - delete a file NCHDIR "path" - change the current directory NMKDIR "path" - create a new directory NRMDIR "path" - delete a directory (it must be empty) NMOVE "file1" "file2" - move a file Saving and loading files: Once the filename has been set using the NFILE command, files can be loaded/saved/executed using the network address 63 e.g Load a BASIC file: NFILE "somefile" LOAD neti_63 Save a BASIC file: NFILE "somefile" SAVE neto_63 Execute a file: NFILE "somefile" EXEC_W neti_63 Save a screenshot NFILE "somefile" SBYTES neto_63,131072,32768 Load a screenshot NFILE "somefile" LBYTES neti_63,131072
