Protocols
͎
Memory mode XON/XOFF
The received characters are stored in a FIFO buffer (first in/first out).
The characters are processed in this buffer.
The buffer capacity can be adjusted from 0 to 128 Kb.
If the buffer is full, the interface signals NOT READY (signal acknowledgement: Level 1, -12 V)
and XOFF (hex. 13, dec. 19). This results in stopping the data transmission. When the FIFO
buffer is empty again, the interface signals READY (level 0, +12 V) and XON (hex.11, dec. 17).
Data transmission can be continued.
In addition, the READY signal is influenced by the status of the printer (On/Off Line). If the
printer assumes an undefined state, the interface also signals NOT READY and XOFF.
͎
Memory mode Robust XON/XOFF
Robust XON/XOFF is similar to XON/XOFF. However, the state of the printer (XON or XOFF)
is also periodically transmitted via the TxD line in the case of Robust XON/XOFF.
