The RS-232 host interface shall have the following characteristics:
Character Set:
ANSI
®
ASCII character set
Word Length:
Selectable 7-bit or 8-bit data format
Handshaking:
XON/XOFF (in receive mode only)
CTS/DTR. Clear To Send (CTS)/Data Terminal Ready (DTR)
ETX/ACK. End of Text (ETX)/Acknowledge (ACK)
ACK/NAK. Acknowledge (ACK)/Negative acknowledge (NAK)
Series 1 Char
Series 2 Char
CTS/DTR. Clear To Send (CTS)/Data Terminal Ready (DTR)
ETX/ACK. End of Text (ETX)/Acknowledge (ACK)
ACK/NAK. Acknowledge (ACK)/Negative acknowledge (NAK)
Series 1 Char
Series 2 Char
Input Buffer:
Selectable from 1k through 16 kbytes. XOFF is transmitted and
DTR goes low when buffer is equal to or less than 25% of full. XON
is transmitted and DTR goes high when buffer is 25% above
empty. Characters are transmitted with no parity from the printer
DTR goes low when buffer is equal to or less than 25% of full. XON
