Reference documentation


The EazyLink popdown has grown into a versatile remote file management tool over the years. Most of the work was done "off-line", recording the version history manually without using a revision control system. Here follows the version history as it is written in one of the source code files (formatted slightly here for easier reading):

Converted to QL Z80 Cross Assembler format, 08.03.91             
Improved and converted to Z88 ROM application format, 18.12.91

V0.241, 10.11.90 - 28.06.91                                      
V0.25   10.07.91                                                 
V0.26   15.07.91                                                 
V0.27   01.08.91                                                 
V0.271  ????????       transmitting ESC B 00 ...                 
                       calling PCLINK II 'Hello' will also install
                       Auto Translation and Auto CR > CRLF conversion.

V0.272  01.10.91       bug in Fetch_RAM_devices: 'File not found' error when current directory 
                       for application isn't the root directory. Wrong device specifier.

V0.273  05.10.91       program crash if Search_filer receives timeout on transmitting files. 
                       IX handle for serial port wasn't re-installed on timeout error.

V1.0    03.05.92       only 512 bytes in segment 0 are used as working buffer. System information
                       are no longer put on a stack and then transmitted, but sent immediately 
                       on each found name. esc_h1_cmd (fetch z88 devices):
                       wildcard is in segment 0 due to a bug in OZ.
                       A '*' is appended to remote wildcard specifies. (request of file names and directories)
                       a 'soft reset' of the serial port is now issued to install the defined 
                       communication parameters in the Panel.
                       in V2 the serial port wasn't 'soft reset' which caused protocol errors since
                       the panel parameters wasn't installed in the serial port driver 
                       (the Panel popdown does this automatically when ENTER is pressed).
                       PC-link II don't issue a soft reset either which means that if the serial port
                       previously had been installed with 'Xon/Xoff Yes', this would cause protocol
                       errors with the IBM PC LINK II program.
