Digi One, PortServer etc. and double enter problem

-
There's annoying problem with Digi RS232 - Ethernet products (also sold BlackBox branded). Many if not most telnet clients are incompatible with their server implementation and treat single enter press as two enter presses. Incompatible clients are at least SecureCRT, Putty and one Microsoft includes with Windows. Teraterm works ok.



You can fix this problem by logging on to Digi admin interface using telnet and typing "set telnetip ip=10.0.0.0 mask=255.0.0.0 mode=striplf". Now connections from 10.0.0.0/8 subnet will work without need for client side hacks. Besides tips on KB for Putty don't even work so you have to use "set telnetip" way. If you can't change Digi setting just press Ctrl-J instead of enter...

Extra Carriage Return or Line Feed When Using PuTTY

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

Convert Huawei E3372h-153 from HiLink/router-mode to Stick/modem-mode [ UPDATED 2016-09-02 ]

-
This is updated version of my original post. I purchased additional modem that's externally identical to old one but had different serial port USB ID (USB\VID_12D1&PID_1442&MI_00) missing from earlier driver pack causing original instructions to fail. I have also included latest Stick-mode firmware 21.200.07.00.805 I've found and corrected some incorrect information on original post. Modern Huawei USB LTE modems can be used in two very different modes. Default is HiLink mode where it functions as router doing NAT and other nastiness much like more traditional 4G routers connected over WLAN or Ethernet. Unsurprisingly default mode is HiLink, but luckily it can be changed to Stick mode getting rid at least one layer of NAT and related issues. Actually there's also third mode which is subset of Stick, instead of native NCM interface it uses legacy PPP over emulated serial port. This can be sometimes useful with older routers with USB port but you won't be able ...

Windows 10 install from USB to Dell Latitude 10 Tablet

-
Dell Latitude 10 Tablet, identified as ST2 Late-2012 by Dell, really sucks. It's shipped with very first Win 8.0 build and after two years of updates it's barely usable with Win 8.1 + all available updates and fixes. I wanted to give Windows 10 try on it as already being worst tablet ever it can hardly get any worse, right? Reinstalling Win 8.1 goes exactly like Win 10 so below applies to both.
