White Paper

S27 Bitmapped Register

Selects the data bit(s) you want the modem set on, and sets S13 to the total of the values in the Value column. For example, ATS13.0=17 enables bit 0 (value 1) and bit 4 (value 16). Software compatibility mode (128) forces "9600" connect message for V.32 connections greater than 9600 bps for some software which cannot accept these messages.

1 = V.21 mode

2 = Disable TCM

4 = Disable V.32

8 = Disable 2100 Hz

16 = Enable V.23 fallback

32 = Disable V.32bis

128 = Software compatibility mode

S28 V.32 Handshake Time

Sets the V.32 handshaking time in tenths of a second. A value of 0 eliminates V.32 answer tones for a faster connection, while 255 disables all connections except V.32 at 9600 bps.

Range: 0 - 255

Default: 8

Units:

0.1 seconds

S29 V.21 Answer Mode Fallback Timer

Sets the duration, in tenths of a seconds, of the V.21 answer mode fallback timer.

Range: 0 - 255

Default: 20

Units:

0.1 seconds
