[Elecraft] Ethernet serial servers... Re: USB to serial angst

[Lee Buller]

I have had experience with Lantronix products and the Ethernet to 
Serial device.  Lantronix does know both areas...serial and ethernet.  I used these devices connecting Laboratory devices (chemistry - Blood 
Analyzers, and a host of other critical hospital laboratory devices) to 
the network which were them access via the software running on the 
server.  The program could read and write to the medical equipment very 
well and worked in critical applications all through an IP address on the 
network.  

These were critical systems....information that were 
sent to Docs to treat patients.  It went perfectly.  I would think that 
these devices would be perfect to controlling a rig on a network.  In 
the medical field, we were not worried about timing latency because it was not "super-real-time" as it would be in sending Code or 
Voice.  We were sending chunks of data.  So, your mileage may vary.  I 
do have a lot of confidence in the Lantronix products and customer 
support was superb.

Hi Don,

Several of us are playing with Ethernet hosted serial servers that plug 
into a router and have a one or more serial connectors. Put the serial 
server at a remote site like a repeater site with internet then run 
redirecter software on your local computer. Poof, you have one or more 
serial ports tunneled across the Internet. No computer needed at the far 
end. We have two different brands with two serial ports. Planning to 
connect a TNC and a repeater controller this way.

Is this what you mean by a plain Ethernet to serial converter?
