Software serial port loopback on linux -


Currently I need to develop some programs that will communicate with Cisco devices on the serial line. I want to build a testing environment on my development Linux machine. So, I got the mobility of the sync emulator, this emulator could provide the interface through the serial line with the option '-U / DEV / TTI 0'. Well, this causes mobility to open the hardware serial port and communicate through it. I can connect from this hardware serial port to another Linux machine with a serial client like MiniCom.

However, since I am using virtualboxes for both Linux machines, I am linking to serial ports through the ability to forward virtualboxes. Serial Port for Named Pipe This scheme is working, but it is very typical I am looking for a method to run mobility and minicom on a Linux machine.

I found that the pseudo terminal can be useful in my case. But I have tried to run the dynamics with'U / Dive / PTX 'and then created with minisque / dev / pts / ... port and its exact opposite. In both cases, I get input / output error on both sides.

Unfortunately, modern pseudo-terminal is not that easy posix_openpt () or After opening the master with open ("/ dev / ptmx") , you must call grant () and to unlock () master Before FDC and its related slave tools are usable ( OpenPT () etc. Utility functions make it easy.)

As an alternative solution, anytime useful It is possible. $ PWD / PTU / Pty / Pty / Pty: $ PWD / PT-Pipe and Dynamics - U $ PWD / PTS # Terminal 2 Socket Unix: $ PWD / PTM-Pipe -

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
