AC International MTA128ST-USB manual Registers, Register Summary

MultiModemISDN User Guide

S-Registers

S-registers are sections of memory in which values are stored that affect how the MTA128ST-USB operates. S-registers are so-called because each has a name that begins with the character S. Use the S command to assign a value or to read the current value of an S-register. To assign a value to an S-register, use the command Sr=n, where r is the register number, and n is the value you want to assign, e.g., S7=45. To read an S-register value, use the command Sr?, where r is the register number, e.g., ATS7?.
