Unofficial Name: GetByteOrBoot
BCALL Address: 807B
This BCALL receives a byte from the link assist. If it is unsuccessful, it displays an error message, waits for a keypress, and boots the calculator (clearing all RAM or waiting for a valid OS).
- C: byte received
If a validated OS is not detected, this routine will wait to receive one instead of resetting RAM.
This routine uses only the link assist, so do not use it on an original 83+.
