Linux COM?

mrtedweb · 05-14-2009, 12:02 PM

Hello everyone,

Is there an equivalent to Windows COM? I have two applications that need to talk to each other across a network. I have no idea where to begin and really hope somebody can answer my question.

I've been assigned the task to redesign this application from the ground up and I have been considering Linux with Mono as a viable option. Any suggestions?

Thanks!

First you really need to give some details.

What are you trying to do? What distro are you using?

If you are just trying to transfer data, ssh is easy in most distros.

I do not use Win. I assume that by COM you mean com ports. In linux you need to look at your /dev/ttySx (where x is a number).

Hard to suggest anything, really, given what information we have. You have two applications that need to talk across the network?? How? What protocol? What port? What do the applications DO? What does this network traffic do?

The question is a bit vague....Mono is a .NET implementation, just another programming language.

Thanks to everyone for your help!

I finally realized I need socket programming (thanks to Sergei Steshenko). My client is looking for a magic bullet that will reduce their current costs as well as help with maintenance issues. Obviously my first thought was Linux (I'm starting with Ubuntu). I'm needing a little push to get me started as the current application was built with Visual Basic (ugh).

netcat is good for quick-and-dirty data transfer within a network.

man netcat

i am confused by how com plays into this. microsoft command object modules are atiquated self-contained dos executables replaced by windows pe (portable executable) *.exe's.

linux uses elf (executable and linking format).

oh wait you are talking about com port (usually refered to as a serial port) ?

Quote:

The serial ports are named ttyS0, ttyS1, etc. (and usually correspond respectively to COM1, COM2, etc. in DOS/Windows). The /dev directory has a special file for each port. Type "ls /dev/ttyS*" to see them. Just because there may be (for example) a ttyS3 file, doesn't necessarily mean that there exists a physical serial port there.

i presumed you meant you are connecting via an ethernet network.
