Anyone know how use Porttalk program, to acess serial port on windows Xp? I have a program that works well in W98, and I want do this work in WinXp, without change my serial component. My program source is in Delphi 5.
 

porttalk delphi

I think porttalk is not necessary to work with serial port on XP, I use but to Parallel Port, to parallel Port LPR 1 I use: C:\>allowio Test.exe 0x378 or C:\>allowio Test.exe /a
will grant test.exe exclusive access to all ports. However if you use

change text.exe by your file name
 

porttalk xp

But for other persons use they will have to access EXE by DOS prompt. It's so difficult .... but I can make an pre-window that create an BAT file to execute main EXE ... I would like to access using a SYS or DLL file ...
 

install porttalk

One way is to install PortTalk's driver, and then use its "allowio" utility to temporarily open the desired ports and run your application. Allowio may even install the driver automatically.
 

installing porttalk

PortTalk and UserPort are both for Windows. I wasn't happy with UserPort. I forget the details - it's been too many years.

Several other Windows port access drivers listed here:
**broken link removed**

I eventually wrote my own kernel mode port I/O driver, because I needed a feature that none of the available drivers provided. (Faster multi-byte transfers.)
