TECHNICAL REFERENCE
S Registers
Note: To change a setting use ATSr=n, where r is the register and n is a decimal value from 0 − 255 (unless otherwise indicated).
Register Default Function
8-14
S13 0 Bit-mapped register. Select the bit(s) you want on and set S13 to the total of the values in the Value column. For example,
ATS13 = 17 enables bit 0 (value is 1) and bit 4 (value is 16).
Bit Value Result
0 1 Reset when DTR drops.
1 2 Reset non-MNP transmit buffer from 1.5K to 128 bytes.*
2 4 Set backspace key to delete.
3 8 On DTR signal, autodial the number stored in NVRAM at position 0.
4 16 At power on/reset, autodial the number stored in NVRAM at position 0.
5 32 Reserved
6 64 Disable quick retrains.
7 128 Disconnect on escape code.

The 1.5K-byte non-MNP buffer allows data transfer via XModem and YModem file transfer protocols without flow control. The 128-byte option lets remote
users with slower modems keep data from scrolling off their screens. When remote users send an XOFF (Ctrl-S) and you stop transmitting, the data in transit
from your modem’s buffer won’t exceed the size of their screen or overflow their modem or printer buffers.
S14 0 Reserved
S15 0 Bit-mapped register setup. To set the register, see instructions for S13.
Bit Value Result
0 1 Disable ARQ/MNP for V.22.
1 2 Disable ARQ/MNP for V.22bis.
2 4 Disable ARQ/MNP V.32/V.32bis.
3 8 Disable MNP handshake.
4 16 Disable MNP level 4.
5 32 Disable MNP level 3.
6 64 MNP incompatibility.
7 128 Disable V.42 operation.
