V.29 multipoint network and is recommended for a control modem as
well.
Register has the following values:
0 = Disable
1 = Enable
The factory setting is Disable.
S93 V.29 Retrain. When enabled, the modem transmits a training
sequence whenever it receives one. This configuration option should

0 = 10 milliseconds
1 = 20 milliseconds
2 = 50 milliseconds
3 = 100 milliseconds
4 = 200 milliseconds
