Parallel Port

[Hank Jedema]

I had to install E-Prime 2.0.8.90 on some newer PCs (Dell Optiplex 390) which lack a integrated parallel port. I do need the parallel port to send signals to external equipment (just output, no input needed), so I installed a parallel port adapter card (StarTech PEX1PLP) in the PCIe slot, which seems to configure properly under W7: It is listed as LPT1 in the device manager, shows 2 lines on resources tab: I/O range 4010-4017 and I/O range 4000-4003, and is "working properly" according to W7. 

Normally, I address the parallel port in E-Prime with an inline "writeport &H378, value" but hat does not seem to work (measured with voltmeter at the parallel port connector pins 2-5). At this point, I am wondering whether I have to address the port on the adapter card in a different manner than the traditional, integrated parallel ports.  I looked through the parallel port info on the E-prime site and posted a question with their support but have not heard back yet. Does anyone have experience addressing parallel ports on adapter cards with E-prime ?

Thanks very much for your help,

Hank,

On my machine, Windows shows LPT1 at I/O Range 0378-037F and
0778-077F, and E-Prime addresses it through &h0378. On your machine,
what happens if you have E-Prime address the port through &h4010?

As David suggested, I would try &H4010. We also have several StartTech cards that operate on &2010 or &3010, depending on the hardware configuration. (Which correpsonds to the W7 resource parameters.)
