In the XON/XOFF protocol, data fl ow control is achieved by
using XON (DC1) and XOFF (DC3) characters. Message blocks
are not required to be bracketed by the Start of Text (STX) and
End of Text (ETX) characters. However, at power up or after a reset
all characters except ENQ or VT will be ignored until an STX is
detected. The message length in this protocol is unrestricted. That

stops when there is no more information.

characters are different than those of the Standard Protocol. If the
host ignores the printer’s XOFF, the printer will resend an XOFF
after receiving every 15 characters from the host.
