7) Receiving buffer: B-EX4T: 6MB
8) Protocol
* XON/XOFF (DC1/DC3) protocol
• When initialized after power on, this printer becomes ready to receive data and sends an XON code
(11H). (Transmission or non-transmission of XON code is selectable by means of the parameter
setting.)
• The printer sends an XOFF code (13H) when the free area in the receive buffer becomes 10K Bytes or
less.
• The printer sends an XON code (11H) when the free area in the receive buffer are 512KB or more.
• When there is no free area in the receive buffer, the printer discards received data which exceeds the
receive buffer capacity without storing it in the buffer. (After detecting the XOFF code, the host
computer must stop transmission before the printer receive buffer becomes full.)
• The printer sends an XOFF code (13H) at power off time. (Transmission or non-transmission of
XOFF code is selectable with the parameter setting.)
• The DTR signal is always “High” level (Ready).
• The RTS signal is always “High” level (Ready).
* READY/BUSY (DTR) protocol
• When initialized after power on, this printer becomes ready to receive data and converts the DTR
signal to "High" level (READY).
• The printer converts the DTR signal to "Low" level (BUSY) when the free area in the receive buffer
amount to 10K bytes or less.
• The printer converts the DTR signal to "High" level (READY) when the free area in the receive
buffer amount to 512KB or more.
