Microsoft Telnet with PortServer results in Double Carriage Return/Line Feed (CR/LF) and Failure to Login


Telnetting into the PortServer (II or TS) is successful, but you may get double CR/LF, so the device on the end of the serial port sees 2 CRs and login fails. 


This is a known issue with the Windows Telnet Client.


1. If you use a different telnet client, the double CR/LF issue should be resolved and a login should be successful.

2. On the TS product line (not on the Portserver II) you can issue the following command as a workaround:

  • set telnetip ip=IP_ADDRESS mask=MASK_VALUE mode=striplf
