Asynchronous Terminals and Printer Processes Programming Manual

TERMINAL I/O
Conversational Mode Characteristics
Moving the Cursor
Use a CONTROL 1 procedure call to execute the various cursor
movements on conversational terminals. CONTROL 1 has the
following parameters:
• 0 = form feed (%014)
• 1-15 = vertical tab (%013)
• 16-79 = skip ( parameter - 16) lines
The terminal must, of course, have the ability to execute the
movements.
Support for DYNAMITE Workstations
For 654x DYNAMITE Workstations, the download manager issues
SETMODE 114 to start or terminate the downloading of 6530
emulation code to the device.
SETMODE 113 allows you to dynamically query for and change the
screen format. The four screen formats are:
• 40 columns by 25 lines
• 80 columns by 25 lines
• 66 columns by 28 lines
• 132 columns by 28 lines
The LIU4 does not have enough memory to support four DYNAMITE
Workstations with screen size 132 columns by 28 lines. Do not
run more than two large-screen DYNAMITE Workstations on an LIU4.
Flow Control Characteristics
Table 2-5 lists the characteristics that specify flow control
and shows how to change them. The flow control characteristics
interact with the modem characteristics, which are described in
"Modem Characteristics" later in this section.
