How did Bourne shell solve missing teletype keys problem?












0














I've learned recently from DigitalRoss's answer that certain teletypes such as ASR-33 lacked certain keys; for instance |. For that purpose in C there exist trigraph operators that can be substituted for | and some others.



Now, this begs the question what was done in Bourne shell back in the day to solve this problem ?
