Thou shalt have no other gods before the ANSI C standard 1359
No, in fact earlier VT terminals (VT-52 for example) had a specific terminal ID...
for doing both terminal type identification and terminal speed determination ... our first transfer of data to mainframe memory appeared to be totally garbeled.
terms out that the line-scanners in the official terminal controller placed the leading arriving bit in the low-order bit position (in a byte) ... so that ascii data was arriving in mainframe memory bit-reversed within a byte. The official ascii terminal translate tables were then handling the bit-reversed bytes when doing
we initially overlooked that when first transfer of incoming ascii data into mainframe memory ... placing leading bit in high-order bit position (within a byte). we quickly diagnosed the problem and fixed the interdata-3 so that it transferred the ascii bytes to mainframe memory in bit-reversed format.
now much later ... mainframes would have two kinds of ascii translate tables ... one for use with terminal controllers where the line-scanners did bit-reversal of ascii bytes ... and another for use with various kinds of things like LAN interfaces that transferred bytes in non-bit-reversed byte format (regardless of the coding type).
