Alternate packing algorithm settings are enabled in Flush Mode. Use the following table to
select Pack Control options:
Note: See Binary to Hexadecimal Conversion on page E-18 for more
information on converting binary values to hexadecimal format.
Idle Time
Idle time to “Force transmit” defines how long the Device Server will wait between
characters before sending accumulated characters, regardless of the recognition of send
characters.
Trailing Characters
In some applications, CRC, Checksum, or other trailing characters follow the end-of-
sequence character; this option helps to adapt frame transmission to the frame boundary.
Send Characters
If send characters are enabled, the Device Server interprets the sendchars as a 2-byte
sequence; if not set, they are interpreted independently.
