parallel port analiser

[peer]

Im new here, dont kill me.

Ive got a project to do where i have to communicate with a i2c chip though a parallel port. what i really need is a program of some sorts that monitors at least 2 lines on the port and shows me the square waves like a DSO. Is there such a thing?

The software at
http://neil.fraser.name/software/lpt/
is quite good. I downloaded lpt.exe and used in in few
Windoes 2000 computers and seemed to work nicely when
I got first thigns checked out.

The thign was the I/O addresses of LPT ports this software uses.
On the computers I had, on both of them, the LPT1 port on the
motherboard was on I/OP address listed for LPT2 in the program.
Selectign that and eveythign orked well.

This software worked nicely with the LPT port on the motherboard.
The extra LPT ports on modern PCs on cards on PCI bus cannot be controlled with this software (they use different I/O addresses), but the parallel ports on extesion cards on ISA bus should work nicely.

Very convient softwae and I can recommend when workign with hardware connected to PC parallel port.
