E C 4 Transparent Printer The default device names to Transparent Printer TP are dev IpX YY that is the prefix name is changed from tty to Ip but the other XYY is the same e g under default device names the corresponding TTY line of dev Ipj11 is dev ttyj11 By multiplexing a serial line there are two sorts of data channels for TTY data by dev ttyXY Y and TP data by dev lpXY Y If the dev ttyj11 is used for a TTY it has to be enabled before you would like to print data through dev lpjll to a printer that connected to the terminal that is operated via dev ttyj11 The channel for TP data that is uni directional is used to transmit the data from a host to a terminal only The differentiates of TTY data and TP data in the same serial line is that TP data are encapsulated within a couple of PRINT ON and PRINT OFF escape strings that are recognized by connected terminals The PRINT ON and PRINT OFF is defined by connected terminals The scheme to multiplex a serial line for these two channels is based on time division method The time slices for TTY or TP data are generated according to the entry procedure polling in the PCCOM driver which is periodically called by system clock The period of system clocks is different among various operating systems e g most UNIXs is 100hz but SCO Xenix is 50hz The interval reserved for TTY or TP channel in the same serial line is important to output TP data to a low speed printer
