how to use porttalk

I've installed porttalk! but when i use c:/porttalk/allowio>allowio 0x378 beep.exe
This is what i get...

AllowIO for porttalk V2.0
Copyright 2002 Craig Peacock
https://www.beyondlogic.org
Address 0x378 (IOPM Offset 0x6F) has been granted access.
Executing beep.exe with a Error in CreateProcess

ProcessID 0f 0
PortTalk Device Driver has set IOPM for ProcessID 0.

My processID is not changing!!

Where's the bug??
Help please....
thank you!

porttalk

what enviroment are you using

if your running windows beep will run alone as the driver allowio
is just dos full mode driver
windows has its own driver so the dos shell will crash with a create error as it cant bind
as you have a dynamic driver conflict windows will exclude the port
till the driver clears memory

windows beep is far more stable

i take it its for an epos system ?? beep exe usualy is

if its apple porttalk then im not sure....

porttalk file

I've never seen allowio give me a ProcessID of zero. Try running a different program with allowio to see if it still gives a zero value.

If the problem is only with beep.exe, can you share the source code and executable so someone else can try it?

how to use port talk

Thanks! I used porttalk successfully for 2 weeks..

I loaded the respective files into the registry, moved the porttalk.sys file into the drivers folder under c:\windows\system32\drivers.

Finally i copied aloowio.exe file into my assembler folder...
And now when i access 8255 peripheral interface using masm611, i get a non-zero process id created without an error in the process BUT my hardware doesn't seem to respond to it!!!

this is how i accessed porttalk....

c:\masm611\bin>allowio.exe c:\masm611\bin\led.exe d090

masm611 is tne macro assembler im using to simulate the 8086 environment and led is my prog's executable file!!

where am i going wrong???

port talk c++

d090 is not a valid hex value. Try 0xd090 instead of d090.

porttalk with a error in createprocess

can i used porttalk with c/c++ in winxp?

porttalk error createprocess

if ur using the correct syntax and u still get a processid of 0 then maybe ur getting the same problem as i did. im a total novice too but maybe u'll get lucky and this will work. just make sure u have administrative rights to the pc it wont work if u dont. to check goto user accounts, click on the name u logged in with and check ur user status
