SEND KEY 63
SEND KEY
SEND (START),(END)
Transmits the block from START to END
inclusive through the serial interface. The FILE
FORMAT and BAUD RATE are chosen in the
SETUP routine.
If handshaking is set to RTS or DTR then those
signals must be true before transmission
proceeds. Assuming that the transmission is
proceeding with regard to RTS, if RTS
becomes false the transmission stops until
RTS becomes true again.
At any point the transmission may be aborted
by the user pressing the keypad ESCape key.
