value is a CARRIAGE-RETURN (%H0C in hexadecimal). This attribute is valid
only when SERVICETYPE is set to conversation mode.

is a BACKSPACE (%H08 in hexadecimal). This attribute is valid only when
SERVICETYPE is set to conversation mode.
INTERRUPT
is a 1-byte ASCII value used to send a break message to the process that owns
the break on the window. The default value is a CTRL-C (%H03 in hexadecimal).
This attribute is valid only when SERVICETYPE is set to block mode or
conversation mode.
LINEKILL
is a 1-byte ASCII value used to delete the line being entered. The default value is
CTRL-X (%H18 in hexadecimal). This attribute is valid only when SERVICETYPE
is set to conversation mode.
Considerations for the ALTER Command
The considerations contain information about command use that should be read before
studying the command syntax in detail.
All Objects
Use the INFO command to view the current attributes.
PROCESS Object

ALTER PROCES is a sensitive command.

The value of MAXTERMINALS cannot be changed to a value lower than the
current number of windows in session.
SERVICE Object

All subordinate windows must be in the STOPPED summary state before
SERVICE attributes can be altered.

The SUBTYPE attribute cannot be altered from STATIC to DYNAMIC if
subordinate windows exist.

The ALTER command does not support the SERVICETYPE attribute; a window
has to be STOPPED, DELETED, and ADDED with new attributes.
