Introduction

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.

V1.1 Extended protocol with additional commands included (Multilink V2)
09.06.93 Split up into modules for new Z80 Cross Assembler

V4.2 Serial port protokol algorithms improved.

The wildcard hmust be explicitly spercified, e.g. ":ram.1/dir/*"

V4.6, 22.08.97 ESC "r" command added: Client sets EasyLink Server to delete file on Z88
ESC "z" command added: Client queries EasyLink Server to update (re-load) the translation table

V4.7, 07.10.97 ESC "y" command added: Client requests for Directory Create

(Software handshaking is default when EazyLink is started)
"PCLINK II" blinking message in topic window during PCLINK II protocol

V5.1 Release changes has been recorded in our Git repository and contains the new features to work on File Cards (Flash / UV Eprom).
