Hello all, I have just purchased an add-in 9-pin serial, 8-bit, half-size ISA card...nothing fancy just something to accomplish the task at hand (I hope!!) What I am attepmting to do is add this card to my system in order to provide a COM3 so that I can attach my Apple eMate 300 to my computer at any time without rebooting in order to transfer files. However, I am somewhat bewildered as to why the card does not seem to be working. I am running an ASUS HX chipset motherboard with a Pentium 200 MMX, with all of my devices running off from an Adaptec AHA-2940. I am also running an ATI 3D Pro Turbo + PC2TV (PCI) and a Sound Blaster AWE64 Gold (ISA). I give this information for some clues as to the possible IRQ's & I/O ranges that are already in use by the system. Initially I configured the card for COM3, I/O 3E8 & IRQ 4. Currently I use my COM1, set to 3F8H/IRQ 4 for my mouse & my COM2, 2F8H/IRQ 3, for my external modem. When I booted into NT 4.0 w/SP4, I went into the control panel, opened up Ports & added COM3 with the I/0 & IRQ settings I listed earlier. NT told me I needed to reboot, so I did so. The only weird thing I noticed in the COM ports section was although, COM2, where my modem resides was listed, COM1, for my mouse was not listed. But my mouse is working fine, so I just left that alone. But when I rebooted my computer & opened the application for transfering files with my eMate, it did not recognize COM3. I was not certain if the problem was with the configuration of the COM port on the card, in NT, or if the application will just not recognize the additional COM port. However, I am uncertain how to test the system to see if the COM port is really working. I am familiar with Windows 95's Control Panel where you can make sure there are no conflicts/problems with the device, but I do not know where to look for this same information in NT. So, the only guess I had was that COM3 was having an IRQ conflict with COM1, since both were set to IRQ4, so I switched the card to IRQ 5 & then changed the setting in NT. Again, though, the application did not recognize the serial card. So, I was wondering if some NT guru out there might be able to provide me with a little more information on how to make sure that the card is configured and working properly in terms of I/O's, IRQ's, and making sure NT recognizes it. The only thing that makes me wonder is after I reconfigured NT each time with the card in the system, I never received an error message about an event or device not being able to startup after rebooting, which makes me think the card is working fine and it is only the application that can not see it. -- TIA, Dave C.
