As indicated before- what I keyed is MY experience with UltraTec 1140. I don't use IP/cell phone/computers re telephones.
My TTY plugs into "landline phone jack line".
I am well aware technology has "improved" , however what I keyed is exactly what happens Whether I am "behind" the latest cell phone et al is not a pressing concern of mine.. Comparison to cell phones et al is irrelevant to what I actually do.
As for the Tax department "phone encounter"- the person at the other end did key responses to my query which I read on the screen. I didn't access through 711-Relay service-Quebec.
I am not unduly concerned whether I can key to a "cellphone". using my TTY. Just use this computer rather than my TTY.
Of Course the tax dept didn't use relay - the Tax dept has a dedicated TTY line ( so no relay is needed).
The issue isn't how
you use your TTY. (As a note:using VCO isn't the same as TTY mode at all ... there are phones that only do VCO, and aren't TTYs at all. Your experience is as a VCO user, not a TTY user.)
The issue is that your out of ignorance of what "texting" currently means, you are continually offering incorrect information to people who want to know about cell phone technology and computer technology of which you clearly don't have any personal experience. Furthermore, since you use VCO almost exclusively, you also have very limited knowledge of how TTY to TTY calls are traditionally placed. I have used both, daily, for more than 20 years - clearly you haven't.
I'm really sorry this is such a difficult concept for you to understand.
The bottom line is that when people post or ask if a cell phone can "Text" a TTY or if a TTY can "text" a cell phone - the answer is "no".
They can use a relay service to communicate between the two, however at the present time there is no way for any cell phone to independently "be" a TTY and as such no way for the two devices to directly connect/communicate with each other.
Period.
If you still doubt this is the case - please take the time to contact a local Deaf/Hoh organization, or ask any relay operator, audiologist - or heck another TTY user (if you simply refuse to believe me on some twisted principle).
Spreading incorrect knowledge through ignorance is one thing, however after having been corrected multiple times by multiple people over the years, at this point your deliberate perpetuation of false information is simply deceptive to those looking for answers from people they assume in answering actually know what they're talking about.
