KERMIT FOR JOYCE LOEBL MAGISCAN 2 IMAGE PROCESSOR
=================================================
This is an adaptation of the Terak p-System Kermit to run on the Joyce Loebl
Magiscan 2 image processor. New features added are as follows:
- added ability for the parser to recognize digits,
this enabled a Baudrate command to be implemented
- added a command to set a work disk, set disk #.
- The IO subroutines were put into an unit RS232 and
changed to suit the Magiscan.
- put the parser back into an unit since the Magiscan has 128K
available.
- modified the constants for the screen because the Magiscan only
has 64 columns.
- Added a unit SysUnit to enable the user to interogate the
current work disk and delete files if so wishes.
- Added a unit FileHandle which gives routines for accessing
files for reading and writing, the old version of this didn't
close a file if there was an unsuccessful receive/send this
is now fixed.
- Modified the Buffer empty and fill routines to use these.
- Added the ability to do eight bit prefixing and the necessary
routines for this.
- Have added a new command called TRANSFER ( do a TRANSFER
TYPE <type> ), which enables transfers of image,data,code and
text 'types'.
- There is also image LOAD routine implemented, this allows
the images to be loaded from disk and transfered to the Host
straight from image memory.
Features such as the ability to do 8-bit prefixing should be adaptable back
into the original Terak implementation and derivatives of this.
