What does it mean when you see "vp" or "TTY" after a phone number?
For example: (916) 555-1234 /vp

If you see a /vp after a phone number, it means that number is for "videophone" use.

The /tty indication after a phone number means that there is a TTY in use at that number. A TTY is a teletypewriter or "teletype." This is an electronic device (or formerly a machine) that converts keystrokes into beeps that travel over phone lines. On the other end of the line is another TTY that converts the beeps into typed output. In the "old days" you'd need a wheelbarrow to carry a TTY around. As time went on TTY's became smaller and more electronic. For a while people started calling them TDDs. The acronym TDD stands for Telecommunication Device for the Deaf.

You will still see either term (TTY or TDD) being used in the Deaf World, but I recommend you stick with TTY because it is more popular within the Deaf.

If you look hard enough, you might even see the acronym TT floating around in some government literature. This term stands for "text telephone." That idea didn't catch on in the Deaf community. "TT" looks a bit like the sign for "toilet." So we just kept our familiar "Y" on the end of "TT" and that was that. So, don't use TT. Use TTY.

Discussion:

When typing on a TTY do not use punctuation. Well, don't use "hearing" punctuation--like periods and commas. Instead of a question mark use the letter Q. Don't worry about capitalizing certain letters or words. TTYs generally just use all capitals.

If you use a TTY for any substantial length of time in the Deaf community you get use to seeing and using abbreviations in your typed conversations. For example, "HOW R U Q" would mean "How are you?" This is now very common in the Hearing World, but we Deaf used to do it many years before hearing people got into the act.

Type "GA" when you want the other person to know it is her turn to type. GA means "go ahead" as in "go ahead, it's your turn to type."

Type "GA to SK" when you are pretty much ready to end the conversation.

"SK means "stop keying."

For example if I were having a conversation on a TTY and I typed GA it would
mean it is your turn to talk. If I typed "GA to SK" it would mean "I'm ready to quit." You would type a few parting remarks and type a single SK. Then I would type a double "SK SK," indicating I'm all done. Then we would both hang up.

Greetings Doc!

Hey! I just bought a TTY on Ebay. The phone company is going to have a second line hooked up by Thursday so I can leave it on permanently for messages, etc.
It's a good one I think. A refurbished Ultratec Superscript ASCII 4420. Normally around $250 to $300 for a refurb, I got it for $76. (Ha!)

Hope this one works. Another one I got off Ebay shorted out the first time I tried to use it. :(
You think I'd learn.

Except........this one I just bought? The guy lives in Portland. I'm going to go pick it up. This means accountability!!! He has more, too, so if this one goes south, it's replacement time...

Hi Scott,

That is neat about you buying a TTY. I hope you have better luck with this one than your previous one.
My wife and I hardly use our TTYs any more.
People just email or instant message me.
When she needs to make a call she just uses one of the online internet TTY services.
Are you familiar with online relay?
