USR Courier V.34 Modem Settings

[Last updated 2/20/96]

These are register and dip switch settings of the US Robotics V.34 Courier modem that I have found useful for bidirectional modem setup on Solaris 2.x and SunOS 4.1.3+.

This is the setup I often use for fixed-DTE speed (Sun-to-modem) 38400 8N1, bidirectional (dial-in and dial-out) applications.
