Window Size
[Text Field] The
window size
field corresponds to the host

that can be transmitted before an acknowledgment is required. If this
value does not match the host value, data frames may be missed,
sessions may hang, and/or session drops may occur.
T1 Timer
[Text Field] The
T1 Timer
field specifies the amount of time to
wait for a response to transmitted commands or data before requesting
re-transmission. Normal setting of the T1Timer should be set in the
range of 1 to 3 seconds. A setting above 3 seconds may result in
noticeable delays to responses that must be retransmitted (typically
than 3% of the frames).
