[GreenKeys] Telex/TWX?

[Don Robert House]

Teletype is a contraction of Telephone Typewriter.

TWX is a contraction of Teletypewriter Exchange service.
TELEX has more letters but means the same thing.

When we sold TWX to Western Union they changed the name of both  
services to:
TELEX I  for TELEX
TELEX II for TWX

In house we also used a couple of other terms such as DTWX which  
simply added Dial to Teletypewriter Exchange service.
Then there was a special call control unit that had small lamps to  
monitor the call progress.  It was only experimental and never got  
implemented
Called WADS D  Wide Area Data Service - Dial

I have a question.  But first a story.

Back in the early eighties in installed a teletype link between my  
house and my girlfriend's house.  Those were the days when you could  
call up the telephone company and order a 50 baud line between any  
two points.  When the installers showed up at my place they were  
confused.  "We hate to bother you, we must have the wrong address.   
The order says we're supposed to terminate a teletype line here but  
it's a residence, not a business."  I ushered them in and explained  
the situation.  "Ah!", they saud.  "We will make sure it's an extra  
clean line!"  So Donna and I had our nice little link, complete with  
auto start, well before email was a gleam in the general public's eye.

We went our different ways but always kept in touch.  Tonight she  
sent me an email about the TWX machine she had at an airline she  
worked for.  She asked what the derivation of the term TWX (or telex,  
for that matter) is.  I didn't know the answer.  I'm sure someone  
here does.
