I'm trying to set up some old BBS software strictly as a hobby type of thing. I want to be able to connect to the BBS with regular telnet.
To do this, I'm currently using a TS2 MEI PortServer. The Ethernet cable goes in one side, and an RJ45 to DB25 cable goes out the other and connects to the computer. Thanks to previous help on this forum, I've got that part working.
This particular BBS software supports up to 16 connections. I don't necessarily need or even want to get all 16 connections working, but I do want more than 2.
I found a brand new, still sealed in the box, Digi ISA AccelePort Xem Host Adapter + 8 port Digi 8EM AccelePort DB25 Serial Adaptor (P/N 50000478) on eBay, so I grabbed it up.
The computer I installed the ISA card in has very little hardware in it, so I didn't have any problems with conflicts. I ran the DIGIMAP.EXE DOS program and it found plenty of available memory space. I then ran the UD-RISC.EXE program, and followed the directions in the printed manual to configure the card. Again - no problems, and the card passed all the tests.
The problem I'm having is that I can't connect to the BBS when going through the Digi BOX/ISA card, but I can connect if I just go through a regular COM port. So I know the PortServer part is working, but something isn't working somewhere between entering the 8 port DB25 Box and going into the computer.
My suspicion is that it's I/O port related. The ISA card has 4 dip switches (though only the first 3 are used.) The default is that they are all on, which the book says is 324h. When I go to the BBS setup, it wants the I/O port in HEX, ranging from 0000 to FFFF. Normally I would use 3F8 or 2F8 for COM1 or COM2 respectively, but the Digi ISA card only allows 7 options which are:
Is there a DOS-based terminal program I can run that will let me listen to 324h for raw input/ouput so I can at least determine that data is flowing through? Or does anyone have an idea of how to troubleshoot this?
This post hasn't been approved yet, so I'll add to it now before anyone sees it.
I may have found part of the problem, but I'm out of time for the day and can't mess with it any more. So I'll have to check it tomorrow or the next day.
I thought the ISA card was configured through the UD-RISC.EXE program and that was it. But after a bit more looking, it appears there's an MS-DOS 6.22 driver. The package doesn't appear to have that driver with it, so I didn't think it needed one.
I took a quick look at the DOS driver I found here: http://www.digi.com/support/productdetail?pid=1503&type=drivers
And it has a lot more options. I'm not sure if the card requires a line in CONFIG.SYS, or if you just have to run the EXE to set up the options, and then it writes the options to the card.
Either way, it gives me something new to try when I get the time.
