- I spent last weekend trying to make a Xircom ethernet+modem 28.8 work on what
- I suppose Xircom would call "adverse line conditions". The result was I was
- able to get them to work reliably if I restricted the connection to v.32bis.
- I did this by setting register S110=5 in the setup string. If you are using
- Windows 95 dialup connection you append ATS110=5 to the connection.
-
- The modem would drop the connection shortly after connection. I have found
- some Xircom material where they say
-
- "The Adapter has difficulty maintaining connections under adverse line
- conditions with the following modems:
- Supra
- Older modems utilizing the -021 Rockwell chipsets (such as older
- Hayes Optima and Practical Peripherals)."
