6. Known problems
-------------------------------------------------------------------------------------
6.1 Help file does not work under Windows 2000 or NT Equinox are currently looking into 
this problem.

6.2 Meridian does not support file names longer than 8 characters
This is because Meridian is a 16-bit Windows application and therefore does not support long 
file names. Equinox have developed a new Toolsuite called EQTools which is fully Windows 
32-bit compliant and does support long filenames. Unfortunately, this toolsuite does not 
currently support the Micro-ISP Series III/IV or Activ8r programmers.

6.3 AT89S8252 / AT89S53 ISP problems
i.  There is a known programming issue with all Atmel AT89S devices in 'Serial Programming Mode'. 
The problem is usually that the device can be programmed once and then further attempts always 
fail. Atmel have released a new revision of the AT89S silicon (rev U) which hopefully fixes this 
problem. If you would like to receive samples of this new part to evaluate, 
please contact mcu@atmel.com and ask for samples for the AT89S8252 rev U.

ii. Some customers have found that it takes a long time to program AT89S devices at certain 
PC BAUD rates. Equinox have not yet been able to reproduce the problem, but we are looking 
into it. As soon as we can find the problem, we will atempt to fix it. In the meantime, please 
try reducing the BAUD rate setting to 19,200.
