| Teletypes in Switzerland were ITU V.21 with three modifications:
|
| - 110 baud instead of 300 baud
|
| - not full duplex
|
| - carrier tone
|
| I experimented with a Java application and FFT to try to write a
| soft modem, so I still know the exact specification by heart. Bit
| 1 was 960 Hz, Bit 0 was 1160 Hz, the carrier tone 1060 Hz, and
| there were 2 stop bits. This means, the teletype could transmit
| 11 letters a second.
|
| The carrier tone is special: if someone stopped typing, the
| teletype switched to the carrier tone and kept it on for about 3
| seconds then stopped.
|
| Being not full-duplex Deaf users used a convention so they know
| when they can type. The called party begins typing and ends with
| two stars, like this **. Then the caller knows he can type and
| also indicates the end with two stars. When a party is ready to
| hang up the phone he writes four stars.
|
| This is what my model (Telescrit) looked like:

| Of Deaf and hard of hearing people I know, the young ones (less

| "Deaf" should be capitalized because of the Deaf community's

| This engineer inventor changed my great uncle's life. My great
| uncle got scarlet fever at age 8 in the 1930s and had a fever of
| 108 F and nearly died. Because of nerve damage to his ear from
| the fever, he became completely Deaf at age 11. He learned how to
| lip read on his own and graduated high school when usually people
| like him would typically be excluded. Nothing stopped him. He
| even fished the fertile Pacific Ocean waters for Alaskan Salmon
| for a living, which was obviously extremely dangerous for anyone.
|
| Some of my best memories of my grandmother and her brother (my
| great uncle) as a kid were at my grandmother's house, whenever
| she had a phone call from her brother. Her talking to her brother
| via a physical TTY terminal with the phone handset in the
| terminal receiver was just so fascinating, captivating and
| interesting to see in the 90s as a kid.

| Thanks to people like him now we have a system like CaptionCall.

| talking on the smartphone and looking at real time transcript.
|
| People with that disability now are doing interviews and getting
| jobs. Not possible before. It needs one time investment in a fast
| smartphone.
