Model 3830 S-Registers

S39  Receive Buffer Disconnect Delay

Determines the maximum amount of time the modem can continue to send data in its Receive Buffer to the DTE after the modem is commanded by the DTE to disconnect, or after the modem detects a line disconnect.

Register has the following values:

0 = Disable (Immediate disconnect)

1 = 1 second

2 = 2 seconds

	D	D
	D	D

255 = 255 seconds

S41  Dial-Line Rate

Determines the modem's highest data rate and modulation scheme for operation on dial lines.

Register has the following values:

1 = 14,400 (V.32bis)

2 = 12,000 (V.32bis)

3 = 9600 (V.32bis/V.32)

4 = 7200 (V.32bis)

5 = 4800 (V.32bis/V.32)

6 = 2400 (V.22bis)

7 = 1200 (V.22)

8 = 1200 (212A)

10 = 0±300 (V21)

11 = 0±300 (103J)

12 = 1200/75 (V.23)

13 = 75/1200 (V.23)

20 = 19,200 (V.32terbo)

21 = 16,800 (V.32terbo)

Factory setting is 19,200 (V.32terbo).
