Optional Modifier Descriptions

DSRTIMER affects the use of the CONTROL 17,1 and CONTROL 11 procedure calls.

(See the EnvoyACP/XF Application Programming Manual for further information on

these calls.) If DSR does not appear before this interval expires, the function

terminates with a timeout error, and data terminal ready (DTR) resets. DSRTIMER

defaults to 4 seconds. If n is specified as 0, no timeout occurs and DSR waits

indefinitely.

You can alter this modifier by issuing an SCF ALTER LINE command to the

EnvoyACP/XF subsystem, but not by using a SETMODE procedure call in an

application.

EBCDIC

Specifies the transmission code as EBCDIC.

EXTENDEDCONTROL/NOEXTENDEDCONTROL

Specifies that frames transferred on this line can have extended control fields (2 octets

long). The control field contains the numbers used for link-level sequence checking. In

a standard control field, the sequence numbers are 0 through 7. In an extended control

field, the sequence numbers 0 to 127. This modifier works with the L2WINDOW

modifier.

The L2WINDOW modifier determines how many frames can be transmitted before an

acknowledgment is received. The EXTENDEDCONTROL modifier allows the

L2WINDOW modifier to be set to 127.
