Also ASCII control characters: XON (^S) and XOFF (^Q). https://en.wikipedia.org/wiki/C0_and_C1_control_codes#Device_control tells me: DC1 and DC3 (known also as XON and XOFF respectively in this usage) originated as the "start and stop remote paper-tape-reader" functions in ASCII Telex networks. This teleprinter usage became the de facto standard for software flow control.[13] Greg -- Sent from my desktop computer. Finger grog@lemis.com for PGP public key.
