[PARPORT] parallel emulator??

Hello,

I have a parallel device that needs to use software written for the serial 
version of the same device.

I don't know enough to rewrite the code for this software to work with the 
parallel version so I was wondering if there would be any way to "emulate" a 
serial port that is in fact a parallel port.

Again, I have a parallel device that needs to be a serial device to work 
with the linux drivers. Any ideas for something to emulate this or idea for 
some cheap harware device I could buy would be appreciated.

Thanks very much for your help.

Clay Smith

*ROTFL*

Chris (Clay?), have you ever looked into any linux-parport message?
Even in yours, there's an automatic signature attached:

[PARPORT] packetwriting on a parallel cdwriter

Hi There,

I have packetwriting compiled as the udf filesystem but now I would like
to use it on my external parallel cdwriter.
The problem is you can't mount a pg says the manual.

Any thoughts
Guy

Hi,

You need to check the packet-writing docs. I don't know whether it supports 
parallel-port drives offhand (parport/packet-cd collaboration opportunity? 
 but _if_ it does, (in a nutshell) you'll need to apply the appropriate 
patch to your kernel, configure with packet-writing support, compile, 
install, reboot, install the udftools package, format a CD-RW disc with 
'cdrwtool -d /dev/pcd0 -q', setup the pktcdvd device with something like 
'pktsetup /dev/pktcdvd0 /dev/pcd0' then mount the pktcdvd0 device somewhere. 
And praying a bit might help too.

Seriously, though, if the documentation doesn't help you, the packet-writing 
mailing list <packet-writing <at> suse.com> might be able to enlighten you. You 
can subscribe from the packet-cd site.

Regards,
Stephen

Hi There,

I'm on the mailing list of packetwriting to!
It seems everything is UP AND RUNNING! both new modules are running.

/dev/pktcdvd /dev/pktcdvdO exist!
udf.o exist.
Problem is here in the parallel land!
pg0 is the only thing wich let you writing to if you have a parallel
writer.
pcd act as a cdrom and doesn't allow writing. problem is you need to
mount the /dev/pg0 device wich is not possible according to the manual
of parport.
what can i do?

Re: [PARPORT] packetwriting on a parallel cdwriter

Hi Stephen

First and for all thanks for replying!!!

Yes I tried this is the message after the pktsetup /dev/pktcdvd0 

/dev/pcd0 
drive not ready
:Function not implemented

If I do this pktsetup /dev/pktcdvd0 /dev/pcd1 I get this

Open cd-rom: No such device

I still need help or confirmation that this will not work

thanx in advance

Hi,

I've just had a quick look at the patch for 2.4.19. It appears from a cursory 
skim-read that packet-cd doesn't yet support parallel-port CD-ROMs.

I don't know how hard it would be to add support; the pcd driver is basically 
an ATAPI CD-ROM driver like the standard IDE one, but working through a 
different interface. It might be possible to whip something up by looking at 
the changes made to the standard ide-cd driver and then making corresponding 
changes to the pcd driver. Or it might not. :)

Sorry to disappoint you 

Stephen

I can see this printk() line has been removed totally in the step from
2.4.20-pre5 to 2.4.20-pre6. Goody. (What was it good for then, anyway?
;->)

BTW, I'm still hoping for my Compact Flash parport support (please
refer to my mails to this list with the Message-IDs

128MB CF disk.   Would Grant like to know what kind of "magic" the
DOS driver does? Is there any hope for answers about my data access
problems?

Friendly greetings from Germany,
Moritz  :)
