Flash Patch (wr) 26.08.1990 by The Frontier
-----------
Some of You, who use highspeed or error-correcting modem, will have noticed,
that Flash has big problems with X/Y-Modem upload when you have connected
with a higher speed than 2400/NONE. Such uploads are interrupted by a mass
of errors.
Simple problem. Flash, in opposition to the manual, doesn't use RTS/CTS.
When started, it deactivates your own setting by simply calling Rsconf
without the appropriate setting. So you have problems when uploading with
blocksizes higher 128 Bytes (MNP-modems with 2400 bps normally have a 256
byte nuffer for input). When downloading with Flash, you should have no
problems, because the code is fast enough to store the data between two
blocks without a timeout. Only at 19200 baud it can occure, that you
might have errors. If Flash would use RTS/CTS protocoll, this could work
too.
For the solution of this I have written FLASHPAT, which patches the main-
program FLASH.PRG so that it correctly activates RTS/CTS. After starting
FLASHPAT from the Desktop, you have to choose 'FLASH.PRG' in the fileselector
and then the choice between patching Flash for RTS/CTS or patching it back
to the original code, so that you don't have to have Flash on your disk
two times, but can swith between the settings by simply use of FLASHPAT.
******************************************************************
* Note, that you must not have FLASH packed using something like *
* PFXPAK or DC_SQUISH, otherwhise Flash will not be patched *
******************************************************************
FLASHPAT precautionary tests the program choosen for really being
FLASH. If not, you will get an error message.
Have fun with your stressfree uploads.......The Frontier
