Table 7-14 T15 Command Settings
:T16= n CTS Turn On Delay Timer
Where n is an integer from 0 to 255 (in increments of 12.5
milliseconds). Default is 0.
After DCD and/or DSR have been turned On while connecting,
determines how long the modem waits before turning On CTS.
:T17= n V.32/V.32bis Connection Training Timer
Where n is an integer from 0, 1, 5 to 32.
Default is 0, use dynamic training sequences - equivalent to a
setting of 28.
Controls the length of the training sequences exchanged when
trying to establish V.32 and V.32bis connections.
Reduce the time required to establish a connection by setting
:T17 to a value less than 28; this increases the modem’s
sensitivity to noise on the line.
Reduce the modem’s sensitivity to noise by setting :T17 to a
value greater than 28; this lengthens the time required to make
a connection.
