Does anyone know of software that can present an Ethernet connection to an application as a comm port? I have a control program that uses a GUI interface to control a radio via the com port.

I would like to remote the radio over the internet. Run the GUI interface on the local computer and have the commands go out over the internet. At the remote end the internet connection would intercept the commands and send them to the to the radio via the com port.

Perhaps what I'm asking for sounds simple, but is actually more complex. Here are the options I have considered:

TCP/Comm from TALTech can do the job, but I have to go out through a serial port across a cable and back into my PC on a serial port and then out through my Ethernet card.

Lantronix Redirector software does is almost what I am looking for but I would like a software solution on both ends of the connection.

Thank You

Have a look at the RSIP-7100 serial to Ethernet converter available from Audon Electronics. The RSIP-7100 serial server is designed to connect a serial device, either RS-232 or 422 or 485, to your network. This allows a remote PC or Terminal to monitor, configure, manage and send or receive data to/from the serial port device via the LAN. After the quick and easy software installation, a new Comm port will be created on your system.

You woud have one RSIP-7100 at your PC end connected to your LAN and another at the radio end to convert back to RS232

See http://www.audon.co.uk/7100.html for more info.

 

Hi Andy:

Take a look at www.beck-ipc.com.

Select IPC@CHIP.

This is a little and cheap PLC with TCP-IP port and web server capabilities. Due to its low price, is often used as gateway from RS232-TCP/IP.
Quite interesting.

Hope useful.

Others Ethernet to serial converters products :

Moxa NPort Server Lite
Digi One IA Realport

These Ethernet to serial converters are designed to connect a serial device, either RS-232 or 422 or 485, to your LAN.

You need only one Ethernet to serial converter. A driver, installed on your PC, works as a dedicated port redirect driver, enabling your application on Windows hosts to transparently access the ports on Ethernet to serial converter as if they were physical COM ports.

 

You might check out ATOP Technologies (http://www.atoptechnologies.com/). They may serial to I/P servers that work pretty well. I think you may be able to have PCs at both ends though I have not tried it.

Try doing a search first. I searched for a "serial port ethernet converter" and found this very quickly.

Lantronix is a software company founded on serial-to-Ethernet converters.

I don't really follow your description, but I guess you're implying that the GUI interface program is limited to using a comm port, i.e., it doesn't understand network connections.

I've worked with radios with serial interfaces accessed over the Internet using a variety of "device servers" or "terminal servers". An effective solution can be made using a PC running Linux (or other suitable os) running the following perl code whenever a connection is made to some configured network port:

#!/usr/bin/perl
select((select(STDOUT), $| = 1)[$[]);
select((select(STDIN), $| = 1)[$[]);
exec 'cu -s 19200 -l /dev/ttyS0';
die "$0: Can't exec cu: $!\n";

That snippet is from the "Modem Sharing mini-HOWTO" by Friedemann Baitinger, and there's also discussion of finding and using "comm port redirectors" on a Windows PC.
