4.16 ETB Switch Option (24)

The end of text block (ETB) switch option is normally set to disable, and all message

blocks end in ETX. If you need blocks to end with ETB instead of ETX, enable this

option. Then when a text block is too large and must be divided into smaller blocks, all

blocks end in ETB except for the ﬁnal block, which ends with ETX.

To set this option using the DLI conﬁguration ﬁle, use the

etbEnable parameter; for

example,

etbEnable = “no”. See Table 5–1 on page 104.

4.17 DSR Delay Option (30)

This option determines the delay in seconds between the time FMP detects a loss of the

data set ready (DSR) modem signal and the time this loss is reported to the client appli-

cation program. This option is designed for use in systems where momentary losses of

the DSR signal are common.

When the FMP software detects a loss of the DSR signal, it delays for the speciﬁed num-

ber of seconds before reporting the loss with the

DLI_ICP_ERR_DSR_DOWN error report. If

the DSR signal returns before the delay time expires, the timer is reset and no report is

made.

To set this option using the DLI conﬁguration ﬁle, use the

dsrDelay parameter; for

example,

dsrDelay = 3. See Table 5–1 on page 104.

4.18 Line Mode Option (33)

The value you use for the line mode option determines the general protocol category

(bisynchronous, asynchronous, or isochronous) of the communication line. Table 4–1

at the beginning of this chapter lists the available line mode settings and their values.

Note that there are multiple settings of the asynchronous line mode, including one

especially for the Bonneville market feed. Refer to the protocol descriptions in

Chapter 2 if you are unsure of which line mode to use for your market feed.
