Modem Initialization Strings
This appendix provides tables that contain modem initialization strings and sample modem
initialization scripts. Table 50 lists required settings, and error compression (EC) and compression
settings for specific modem types. Use this information to create your modem scripts. Table 51 lists
information for setting AUX ports. SeeTable 52 for a legend of symbols used in these two tables.
Sample scripts follow the tables.
For information about configuring lines to support modems, see the chapters in the part “Modem and
