Diamond SupraExpress 56i Sp
Posted on 1998-07-28
I'm trying to install a Diamond SupraExpress 56i Sp. I've never seen a modem be so troublesome. Here is the problem:
Old modem has been removed from my system in both hardware and software. It has been removed from both modems area and system area [device manager].
When the new is installed [hardware wise] the motherboard BIOS detects it during bootup...Windows95 detects it and prompts for the driver disk...all is well [so far]. The modem gets installed on COM3 with an IRQ of 12. I have a mouse on COM1 using IRQ4 and just the standard COM2 serial port using IRQ3.
When I try to use the modem it says that it's being used by another dial-up networking connection. When I try to do modem diagnostics it says "cant open port."
I've tried re-jumpering the modem [instead of plug and play] to set it at a fixed comport and IRQ. My old USR 33.6 sportster was jumpered for COM4 IRQ3...this new modem does not have that available jumper setting...instead I have A0-A5 jumpers which allow a lot of possible configurations but do not allow COM4 IRQ3...the COM4 jumper settings only allow IRQ's higher than 7.
I've tried manually re-setting the IRQ's for plug and play in Windows95 but to no avail...if the plug and play is setting the modem's IRQ to 12 shouldn't it work ok? I do not have a PS/2 mouse which is what IRQ12 is reserved for..
Also...with my other modem I noticed that there had to be a COM4 port added into the system before it would recognize the modem and then assigned to that port....apparently this one does not work that way...I've tried adding a COM3 and COM4 but it just kicks the modem over to COM5...I've tried manually adding the modem on COM4 and assigning it to an existing COM4 port but none of this works....I've exhausted all possibilities that I know of.
What happened to the good 'ol hardware jumpers for the COM and IRQ setting? This plug and play isn't all it's cracked up to be....in my personal experience....I'd be surprised if more than 1% of these modem worked on "plug and play" setting right out of the box....I am about to rename this to "plug and scream."
Any help that anyone can give would be greatly appreciated. Thanks.
