2.6 Serial Input/Output
If BUSY control is selected:
When 236 bytes of data have been stored in the input buffer, the SBUSY
signal becomes high to request that the computer temporarily stop sending
data. When the amount of data stored in the input buffer becomes 235
bytes or less, the SBUSY signal changes to low to request that the host
device continue data transfer. Up to 16 bytes of input data are guaranteed
after the SBUSY signal has become high. When an error occurs, the
SBUSY signal becomes high. Data input is prohibited until the error is
cancelled.
If Xon/Xoff control is selected:
When 188 bytes of data has been stored in the input buffer, Xoff (13
16
) is
output through the TxD terminal to request that the host device temporarily
stops sending data. When the amount of data stored in the input buffer
becomes 124 bytes or less, Xon (11
16
) is output to request that the
computer continues data transfer. Up to 64 bytes of the input data are
guaranteed after
Xoff has been output. When an error occurs, the Xoff signal is output to
prohibit the data input.
When the error is cancelled, Xon is output.
2.6.1 Serial data transfer
The PRN607-S transfers various data other than the Xon and Xoff codes
which are output when controlling Xon and Xoff.
Regardless of whether the input mode is serial or parallel, the following
data is transferred through the TxD terminal.
(a) Error codes when a hardware error occurs at initialisation
