Ascend Pipeline 25, 50, 75, 85 and higher
We are receiving many questions about the pipelines in our mailboxes:
If you have any trouble to get something on your screen, try all known baudrates at your com1 and the serial port of the pipeline.
If there is no response, the Pipeline is dead - through it away.
Dont spend any money in a pipe 25 to 75.
Specially the Pipe 25 is a very old model from 1994 and has very few features, not even NAT. So you cannot use it as a modern dial-in ISDN router. Because of its small flash size, there is no chance to update any better TAOS.
