MODEM.INF Settings for US Robotics Modems

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1
• Microsoft Windows NT Workstation version 3.5
• Microsoft Windows NT Server version 3.5

SUMMARY

US Robotics has a file available containing updated MODEM.INF settings for use with all of their modems. These MODEM.INF settings have been tested with the Remote Access Service (RAS) software included with Windows for Workgroups 3.11, Windows NT version 3.1, and Windows NT version 3.5. The file, MDMUSR.INF, can be downloaded from the US Robotics BBS at (847) 982- 5092.

MORE INFORMATION

Enclosed is the contents of the file MDMUSRV2.INF. To use this file, you can either rename it to MODEM.INF and place it in the \WINNT\SYSTEM32\RAS directory or add the settings to the existing MODEM.INF that ships with Windows NT. In either case, be sure to backup the original MODEM.INF before making changes.

If you choose to add the settings from MDMUSRV2.INF to the existing MODEM.INF, be sure to delete or comment the original US Robotics sections included in the MODEM.INF.

; 10/25/94 - modified to include PCMCIA aliases ; 12/12/95 - modified to allow 33.6 connections ; - MAXCONNECT jumped to 57600

;          - COMPRESSION_ON changed to &K1
;          - &a3 changed to &a1 to eliminate superflous result codes
