Register Descriptions
:T16=
n CTS Turn On Delay Timer
Range:
Where n is an integer from 0 to 255 (in increments of 12.5 milliseconds)
Default:
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
Range:
Where n is an integer from 0, 5 to 32
Default:
0, use dynamic training sequences – equivalent to a setting of 28
This register controls the length of the training sequences exchanged when trying to
establish V.32 and V.32bis connections.
Reduces 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.
Reduces the modem’s sensitivity to noise by setting :T17 to a value greater than 28;
this lengthens the time required to make a connection.
1
Raising DTR does not force the modem off hook in
leased-line mode when the modem is idle,
regardless of the &D setting
5
0
No synchronous clocks until connection
1
Synchronous clocks always On (only valid in
synchronous by switch)
6
0
DCD LED follows connection status
1
DCD LED always follows modem carrier when
&C1 is set
7
0
V.32 answer tone without phase reversals
1
V.32 answer tone with phase reversals
