Thats correct for the older teletype machines.
I am using the ASR33 which is 110 N82 and uses ASCII. Many of the older TTY machines were Baudot Code. 5 bits 1.5 stop bits.
I think the Ham Radio users gave a rebirth to the use of Baudot.
The ASR-33 was originally built with a dialup 110 baud modem. I had one in my office that would reach our mainframe.
Then the hardwired them to the computer using the 20ma current loop. When the later DEC computers came around, so did CRT terminals. The ASR33 started being made in various versions where some only printed. They were still slow, and difficult to type on. You had to have a special technique to type on an ASR33 because the buttons had to be depressed about 3/8 of an inch and they were very mechnical.
It seems to me that the 300 baud modem started really making the ASR33 obsolete. Then the Decwriter LA36 that could go 30 cps (300 baud) came around. The ASR started getting pushed in the corner.
110 Baud data is 10 CPS but 2 stop bits (110 N82), therefore 11 bits transmitted per word. At 300 Baud with only 1 stop bit, we are only transmitting a 10 bit word. 300 N81
I have had an ASR33 around for about 50 years. Once in a while I get it out and get it going. My current unit is straight RS232. It will plug right into the serial port on the back of my PC (yes the PC is a little old). You need a real windows PC Serial Port. The USB Dongle Serial Adapters will not go 110 baud, I think for the same reason the Arduino will not.
Getting my project working again where the ASR33 can play command line games such as CAVE ADVENTURE should be fine after I clean up and lubricate the ASR33. I is a full duplex terminal so a loop back DB9 shorting 2 to 3 should allow me to exercise and fully test the unit before making it a terminal on my PC and talking to it with PUTTY.
After that, I will go after bit bashing a 110 baud output from an Ardruino and get the unit to print the alphabet and THE QUICK BROWN FOX... BTW ASR33 only does upper case.
Ribbons and paper are easy to get for these units but not so easy, 1" Paper Tape. Somehow paper tape has fallen from use. It used to be used on machine shop equipment as well in the motion picture printing business it was used to do color correction from scene to scene.
I should be able to find some 1" paper tape somewhere.
