CloneClock
DOCUMENTATION
** PREFACE
If you don't have two computers set up in Parnet, you dont need this program,
so go delete it NOW!
** WHAT THE H**L IS IT?
Now that you ask so nicely I might as well tell you!!
I have a A2000/030/882 + FPU and lots of other stuff, AND a CDTV. These two
computers are set up in a Parnet Network. In contrast to my A2000 The clock
in the CDTV has a bad habit of resetting itself to some odd time like
09-oct-88 and the clock on the front display says: 12:00. As time went by I
got kind of tired of that, so CLONECLOCK WAS EVENTUALLY BORN!!!
CloneClock simply copies the exact time on the computer on which the proggy
is executed and installs this time on the other one. And you have the correct
time on both computers.
** REQUIREMENTS
1. The program CloneClock ;-)
2. A running Parnet network
3. 'Netcmd' on the Amiga where you run CloneClock (tm)!! 'Netcmd' is a
command within the Parnet Package if you didn't know!
4. The AmigaOS commands 'Date' and 'Setclock' on the amiga where you DO NOT
RUN Cloneclock , -namely the one with the f**ked up time!!
5. Bad timing on one of your computers. :-)
** PARAMETERS
There can be only one!! Parameter that is!!
The parameter in question is a number between 0 and 9 which is used to
specify a delay in seconds. This delay is however crucial for otherwise
the Netcmd command might gets too many jobs on its hands. If you care to
read the PROBLEMS section you will know why this delay is so important.
You're free to choose a number between 0 and 9 in order to specify the
delay. On my two Amigas 4 seconds works fine - every time!! The delay
naturally depends on whether the command has to be loaded from a shitty
diskdrive or a wonderful harddisk. Since my CDTV unlike my A2000 does
not have 560HD space I have to wait for the disk drive to finish.
Then again, if you code a VERY quick loader you might want to set the
delay to 0!!!
** PROBLEMS
*I have however observed a remarkably great instability during transferring
the commands to the other Amiga using Netcmd.
SnoopDOS points out that some weird background task (probably some effect
from Netcmd) tries to execute a file called command.pkt twice. The way I see
it, there seems to be a BIG problem with the timing in the Netcmd command.
It saves a file in net:ram/ called command.pkt as a result of the first
command. If this command.pkt has not been removed when the 2nd arrives
things f**k up and you get a message saying something like: 'Can't open
command packet'.
I'm not sure Netcmd checks for another command being issued before creating
another one - I dont thing it has anything like a chain or waitup mode!
*If anybody finds out how to check for Netcmd being done issuing the command
and when it has removed the command.pkt file, then I would be very grateful
if you'd tell me - so that I could release a Watching-out-for-bug-in-netcmd
version.
** SHIT YOU NEED TO KNOW
*I have included the source in ASM in case you have problems and want to
change it yourself. You dont need to be an assembler freak who remembers
all OP codes in hex for the instructions sets on all motorola processors to
firure out what it does!!!
*I didn't try it out the other way around from CDTV to A2000 because the
code is totally system friendly. There should be now problems coz I execute
it from a 030/KS 2.04 to 000/KS 1.3, so I mean, if anything could go wrong
it probably would have already!!
