6100 MPS-B Programming Manual

INTRODUCTION TO 6100 MPS-B
Line Configuration Options
NOTE
The modem CONTROL Connect and Disconnect requests require
that the value of MPSBCONNECTTIMEOUT be a value other than
zero.
In general, the value should be very short for a leased line,
because in that case the modem asserts DSR almost immediately.
In the case of a switched line, with the LIU on the receiving
end, the value should reflect how long it will take for a call to
come in. If the LIU is on the calling end--with an operator
dialing--the value should reflect how long it takes for the
operator to make the connection.
MPSBTIMEOUT (1 word) specifies the interval, in 10-ms units, that
MPS-B waits for a station to respond to a poll or write sequence.
If the station does not respond within the time interval
specified, MPS-B retries the operation until a proper response is
received, or until the retry count (see MPSBRETRIES) is
exhausted.
The value can range from 0 through 32767. The default value is
270 (2.7 seconds).
If the value specified for MPSBTIMEOUT is zero, timeout is
immediate.
MPSBPOLLINTERVAL (1 word) specifies the interval, in 10-ms units,
that MPS-B will wait between two consecutive passes through the
polling list.
This value can range from 0 through 32767. The default value is
zero (no wait).
If the value specified for MPSBPOLLINTERVAL is zero, MPS-B will
poll continuously, with no wait between passes through the
polling list.
MPSBRETRIES (1 word) specifies the number of times MPS-B will
retry an operation, such as poll (except timeout) or write,
before terminating the operation abnormally.
The value can range from 0 through 32767. The default value
is 3.
If the value specified for MPSBRETRIES is zero, no retries occur.
