Z88 PCLink Client - an experiment

PCLink2 Client

My previous work on Z88 serial communications was OK, but you need to use the Z88 and Windows at the same time – meaning that you need about 4 hands.  You can also only send one file at a time.  However, it does work with an out-of-the box, unexpanded Z88 without any additional EPROMs, which is why I wrote it.

But ... a lot of Z88’s have a PCLink2 or EasyLink EPROM installed.  This makes the Z88 act as a server, meaning that all the work could be done from the PC (with some client software).  So ... I’ve decided to have a go at developing a modern Client for that - one that will work on current versions of Windows.  After speaking to Vic from Rakewell we decided that it would be good to have the Z88 act like a memory stick ... to simply appear as a new drive in Windows.  You can then just use Explorer to access your Z88.  But can that be done over a serial connection?  Well I think so ... with the help of a library like Dokan.

So this is my proof-of-concept.  I have tried it on Windows 7 (both 64 and 32 bit versions).  It only uses the PCLink2 protocol, which should work with both PCLink2 and EasyLink EPROMS, but has limitations - it cannot create directories on the Z88 for example.  It works with the ‘official’ Z88 serial link cable.  When the client is running it puts a Z88 icon into your system tray.  Right clicking this icon allows you to browse to the Z88 or exit the client program.

You must connect the Z88 and run PCLink or EasyLink before starting my Windows client software.

Configuration options
There is a Z88.ini file which allows you to set the COM port and the protocol used (at the moment only the PCLink2 protocol is supported).  But you’ll need to edit the Port= setting in the .ini file if you’re using a COM port other than COM1.

WARNING!! this is a proof-of-concept and is very experimental.  It could crash your PC or corrupt the files on your Z88.  I’m only putting it here in case some brave people would like to test it and let me know if they find any problems.

To make it work, you will need to install the following components on your Windows machine:

.Net Framework 3.5
Dokan Library (download and install Dokan-0.6.0)
