CSI n1; n2; n3; n4 " r
STX read data ETX
n1 =
number of reading attempts
n2 =
reading threshold
n3 =
reading block number
n4 = reading error (0 = without error)
When the execution of the command CSI " r
is without error, the read data contains the
value for the next free posting line (= 6, see
step 7).
The boundary characters STX (hex 02) and
ETX (hex 03) are also transferred.
CSI # r STX write data ETX
New free posting line = 7, account number
(unchanged) and new passbook contents
(balance) depending on deposit or
withdrawal amount. The write data is
enclosed between STX (hex 02) and ETX
(hex 03).
This MSR write command produces an
acknowledgement in the form of
CSI n1; n2 # r, which is not evaluated in this
program example (n1 = number of writing
attempts needed; n2 = error identification for
read after write check).
