Asynchronous Terminals and Printer Processes Programming Manual

TERMINAL I/O
Conversational Mode Characteristics
Line Termination
The LINETERM SYSGEN modifier and the LINECHAR CMI subdevice
attribute specify the conversational mode line terminator. A
special line termination mode allows you to change the line
termination character. The CMI SPECIALMODE attribute has three
values:
• COUNT--line termination character is included in the read
count
• NOCOUNT--line termination character is not included in the
read count
• RESET--line termination character is restored to the last
value specified by SYSGEN or CMI
The SPECIALCHAR CMI attribute defines a special line termination
character. The I/O process recognizes this special character
when SPECIALMODE is set to COUNT or NOCOUNT. Use the SETMODE 38
procedure call to set and reset the special line termination mode
and to define the special line termination character.
Line Feed Character
The LFTERM, LFSYS, and AUTOCR SYSGEN modifiers determine whether
the system or the terminal supplies the line feed character after
the terminal operator types carriage return.
• LFTERM--terminal supplies line feed
• LFSYS--system supplies line feed
• AUTOCR--transmit carriage return to the terminal if LFTERM is
selected
You can change the SYSGEN-defined value with a SETMODE 7
procedure call. For ATP6100 subdevices, you can include the
AUTOLF attribute in a CMI ALTER SU command.
