CHAPTER 3 Communication Channels 46 Serial Communication The LaserW riter Select 310 printer has two communication ports that support two communication channels.
CHAPTER 3 Communication Channels Serial Communication 47 P ar ity Settings 3 The parity settings for the serial channel may be odd, even, space, or mark.
CHAPTER 3 Communication Channels 48 SCC Operator Encoding XON/XOFF Flow Control 3 XON/XOFF flow control uses two special characters, XON and XOFF , that may be sent either to the printer or to the host to control the flow of characters.
CHAPTER 3 Communication Channels Communication Protocols 49 Figure 3-1 SCC operator encoding Communication Pr otocols 3 The LaserW riter Select 310 printer supports both simple and binary communication protocols for serial and parallel channels.
CHAPTER 3 Communication Channels 50 Communication Protocols The serial and parallel communication handlers perform the special processing of the return and line-feed characters, as described in T able 3-4. This processing is independent of the return and line-feed handling performed by the PostScript interpr eter itself.
CHAPTER 3 Communication Channels Communication Protocols 51 Since any character code can be transmitted as data with this protocol, it can be used for sending PostScript language jobs that contain binary images. Binary protocol is set by default when the LaserW riter Select 310 printer is power ed on.
CHAPTER 3 Communication Channels 52 Communicating with an IBM PC After CTL-A is received, the next character received that is not one of the special characters must be the result of XORing one of the special characters with 40 hex.

CHAPTER 3 Communication Channels Status Queries and Spontaneous Messages 55 T ypically , characters written to the standard output file by PostScript operators, such as print , are not sent immediately . They are buffer ed until a flush is executed.
CHAPTER 3 Communication Channels 56 Status Queries and Spontaneous Messages All messages generated spontaneously by the server (as opposed to those messages produced when the PostScript language pr ogram executes print ) conform to the same syntax as status messages.
