A82: Re: TI-82 Silent Link server


I did locate the build in functions on rom version 19, and if i had a rom
dump of some other versions finding the addr in thos would take  less then
1
min. Since rom dumping on the TI83 is know possible it should be no
problem
to find out how the function is implemented on the TI83 an make some thing
like that. The only problem is error handling. The build in functions uses
the normal error handler (possible also some special error handling
versions
of 8114..8121), and no one has tried using that in an asm program yet.
However i do believe i know how it works, so unless i am completly wrong
it
should not be a problem to implement (if you have the time).
