Transparent Polled Async
Short Timer Duration (#116)
Range: 0 to 255
Default: 0
Description: Selects Short Timer duration in milliseconds (used with #115).
During receipt of an asynchronous message, if a character has not
been received in the time period defined by Short Timer Duration,
the message is determined to be complete and is sent into the X.25
network.
Using a Short Timer instead of an Idle Timer when running high-
speed asynchronous data usually results in better response times
due to the smaller granularity. However, using Short Timer will
increase CPU utilization as compared with the same application
using the Idle Timer.
• 0: Disabled
• 1–255: Duration in milliseconds
EIA Signalling Action (#117)
Range: 0 or 1
Default: 0
Description: This parameter selects EIA Signalling action.
• 0: None
• 1: Raise DCD before transmission and drop DCD after
Message Assembly (#118)
Range: 0 or 1
Default: 1
Description: Message Assembly (#118) controls the transmission of a message
received from the X.25 network to an attached device.
• 0: Disabled. If Message Assembly (#118) is disabled,
• 1: Enabled. If Message Assembly (#118) is enabled, the

message transmission begins as soon as the first packet
arrives from the X.25 network.
entire message is buffered at the remote PAD before it is
transmitted to the attached device. Buffering the message
eliminates the possibility of intercharacter delays being
introduced which could cause the attached device to
misinterpret the end of the message.
