: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.
