Symptom: Trouble Accessing a Port

Introduction

Use this procedure if you are having trouble accessing a Digi One/PortServer TS 2/4 port. The specific problem might be that you cannot logon from a terminal or the printer or modem is not working properly.

Assumptions

This discussion assumes the following:

That the Digi One/PortServer TS 2/4 itself is working, that is, that it completes the boot cycle. If it is not, see "Symptom: Digi One/PortServer TS 2/4 Does Not Boot" on page 18-2.

That the network is working. This is a relevant consideration if the ports you are working with are RealPort ports and if all RealPort ports are not working. The discussion in "Symptom: Can- not Telnet to the Digi One/PortServer TS 2/4" on page 18-3goes through the steps of validating the network connection.
