I have two dos programs they are similar. Under the option CODIFY, first program have posibbilyty to save file to disk and second one dont have that option. Is t posible to insert that option in first program?

Yes i would like.

Any ideas about this "DCU" what's "unavaible"? Might it been connected with some invalid data in incomming data or I just didn't choose right options?

Its just checking device presence, in fact there are two devices DCU and tape recorder. I line on lpt2 goes first dcu, and then from dcu cable goes to tape rec.

i think it is invalid incoming data.

hi again!

No, I was wrong again, I've just missed next commands to LPT(2) port. I catch begin of data stream, see:

"WRFTEST [about dozen of spaces] CO/x1"

(In the example above I selected "TEST" as name for file on tape) It was first packet (size about 15 bytes).

So next my task would be dump all data steam. I've overcame "DCU unavaible" error.

Finally I've done it, at least ver1 can dump data stream to "DCU", see:

Some explanations:

1) L362C3_P.EXE - patcher for L362C3.EXE. Better beware your original L362C3.EXE, it will be change it;
2) if you'll launch L362C3.EXE (updated), it shall dump all data (include handle commands like "WRFPR CO" - write file and LRC (1 byte for each 0x100 bytes)) to special file (dcu.log);
3) I've also included an example which I've got in my researches (I used to use "PR" file as sample).

I have little problem, i have tried this patch but it doesn't dump file, its written saving file wait and then it turns to main menu but i don't see log file.

| Сообщение посчитали полезным:

Plz scan for \SOCK\DCU.LOG.

Also please pay attention: I dump ALL data (which are sent onto DCU - including some pre- commands like "WRFPR" and all packets WITH LRC).

Can you make this patch and for 304?

| Сообщение посчитали полезным:

hi again!

Firstly I wanna ask you: did you watch successful dumping (DCU.LOG)? What can you say about - is it correct/etc? What's about special commands/LRCs?

According to 304: I think YES. But the question: for what? 304 can save file, is it enough or not?

i have seen dump. Like i saw there are three times start of file.
I wont to compare dump from 304 with codified file and see what is the deference between these files, like this i can see what is is the file for 362 correct

| Сообщение посчитали полезным:

hi again!

Yeah, as I promised, I've endured next problem and I've realized next patch - for "304". As usual, this surgery does dump into "SMU.LOG".

The results of mine: patcher&sources&an example from my researches you can find in this attachment:

(include handle commands like "WRFPR CO" - write file and LRC (1 byte for each 0x100 bytes))

Can this be eliminated from file?

I have ida 4.1 vesion is it enought for bigining?

| Сообщение посчитали полезным:

Yeah, it'd probably be enough - the applications is pure from all kind of protection. I'll give you full collection of advises here, including my results (like you can see in my attachment).

But the problem to purify dumps is rather to understand the mechanism of sending data algo than evulse next code blocks from application.

As I've figure out the process of sending data:

1) Send "WRF"/"FPR" commands: it goes:

WRFTEST1 <spaces> CO,0x01 + plus LRC

LRC could be describe by next code:

seg001:1A35 sub10745_GetLRC proc near ; CODE XREF: sub10621_SendBufferWithFileName+20p
seg001:1A35 xor al, al
seg001:1A37
seg001:1A37 loc_10747: ; CODE XREF: sub10745_GetLRC+5j
seg001:1A37 xor al, [si]
seg001:1A39 inc si
seg001:1A3A loop loc_10747
seg001:1A3C mov ds:0C2F8h, al
seg001:1A3F retn
seg001:1A3F sub10745_GetLRC endp

Where ds:si is pointer to data block, cx is a counter of bytes. LRC starts from zero.

2) Write next data blocks (I suppose now that it's just blocks of original file):

<Data block - size is 100h bytes each> + plus LRC (the same algo).

So as variant to solve I can proporse you just eliminate LRC from each packet and erase first "WRF" command from the begin of file.

I suppose my analisis can help you to understand the process of "sending data". Main procedure (I've called it as "subEE29_JobWithPort") performs all necessary functions: port initializing ("I"-function) or send data block ("F"-function), see:
