Chapter 6 - S-Registers
S34
Buffer Length of Command Mode...After On-line Escape Sequence
Unit: ASCII Character
Range: 0-60
Default: 10
Description: If the number of characters after AT exceeds the S34 buffer length value, the buffer
is cleared and the escape sequence is aborted.
S36
Time Between DTR Inactive and Modem Off-Hook
Unit: 1 Second
Range: 0-255 seconds
Default: 0
Description: The DTR Busy-out feature uses S-Register S36 to set the time between DTR
inactive (low) and the modem going off-hook. S36 can be set in one-second intervals
from 0 to 255 seconds. With the default setting of S36=0, DTR Busy-Out is disabled
(i.e., DTR won't Busy-Out).
S37
Time Between DTR Active and Modem On-Hook
Unit: 1 Second
Range: 0-255 seconds
Default: 5
Description: S37 sets the time between DTR being active and the modem going on-hook (not
busy). S37 will only function in conjunction with S36.
S48
Program V.34bis Connect Speeds (2834 Series only)
Unit: N/A
Range: 33, 31, 28, 26, 24, 21,19,16,14,12, 96 and 48
Default: 0
Description: Defines which speed modem connects within the scope of Enhanced V.34 mode
(e.g., S48 = 26 means maximum connect speed is 26.4K). This register
compensates for line conditions that have trouble supporting higher Enhanced V.34
speeds (e.g., 33.6K, 31.2K, 28.8K, 26.4K, 24K...). The modem default is a value of 0,
which indicates a connection attempt of 33.6K.
