This program is totaly freeware. The next version should be in DMA! In DMA I should reach up to 1Mb a second! This program only reaches 500kb a second (in SPP I reached 14Kb a second). Because this is freeware it is intended to stay freeware, so the only thing you can't do is sell it. At the moment I'm trying to do a DMA transfer in Delphi3, but I need to catch an interrupt too (thanx to Mr Gates it is not easy to do and I know absolutely nothing about VxD). So it will take a while before I will accomplish that. Still working on the dos-version though and I hope to get it working soon (DMA!!!). Both Delphi and dos versions should be compatible with each other (except for the long filenames)! Very, very usefull info on ECP-ports: ecp_reg.pdf (a cover letter from Microsoft, at least one thing they did well) Sorry can't remember where I've found it, but I could always mail it to you. Cable configuration: pin----pin 1 10 (nStrobe----nAck) 2-9 2-9 (data-------data) 10 1 (nAck-------nStrobe) 11 14 (Busy-------nAutoFd) 12 16 (PError-----nInit) 13 13 (Select-----Select, not used) 14 11 (nAutoFd----Busy) 15 17 (nFault-----nSelectln) 16 12 (nInit------PError) 17 15 (nSelectln--nFault) The easiest and most secure way to do it is to buy a 'switch box'. It's a DB25 male to DB25 male connector in a kind of small box. Open the box and switch the necessary wires. Now you can use any ordinary parallel cable (DB25 male to DB25 female cable)! Things to do: DMA in dos DMA in Delphi (hard one, because of the ISR) multiple file transfer (got already an Progressbar for it) Send any comments, questions, feedback, silly pictures, absurd mails to: LordXeroth@Yahoo.com You will certainly get an answer. This readme is written on 18th of Februari 1999. Program finaly working on 18th of Februari 1999. PS. Use the things at own risk! I'm not responsible if you blow up your port!
