Forgot to mention as to "Does anybody know what the fastest modem was that was made for an ISA bus?"
USR 5687 Though they list Windows as requirements it's not a Winmodem, and has jumpers
🙂
Yeah, doubt they'd have a floor lower than 14.4. What I was talking about wasn't a protocal problem, but an ISP restriction against slow connections. One here did that, when I couldn't get an old 1200 to connect (in a similar project with a 286 years ago) I called up, they told me they didn't allow anything slower than 9600 since people using slow modems tied up the lines for so long. Least that's what they told me, maybe the tech wasn't clear either and it was about protocals.
SCSI-1 hmm. Interesting. Not the kind of thing you'd expect to find in an old GW2K...I wonder....if it's SCSI or if it's an old Panasonic interface. Uh, here...
this is what I mean.
The MTU - nah, long as your MTU (max transmit unit) is set =< their MTU you're fine. We used to set them lower, in the 500's, trying to hit a number that would multiply to match the ISPs MTU. 508 in this case for example. Anyway doubt that's the problem. Trumpet was a PITA, but once you got the right settings and found the right modem string to get your modem working best with your ISP staying online for weeks at a time were easily doable. Up until the 28.8/33.6 days I had fewer disconnects than I do with DSL now.
No big deal to get an external modem working in W3.1, just make sure you have Com1/Com2 working, if it's got a serial mouse make sure it's on 1 and put the modem on 2, or vica versa. Take out the internal modem so it's not sharing resources. Remember to not to try to run com 1/3 or 2/4 at the same time though
Wishing you continued good luck, look forward to the 'I got it all working!' post.
