Page 18: Dial Security
The account profiles are stored in the host Courier Lite 56K Business Modem’s nonvolatile random access memory (NVRAM). There are two forms of Dial Security; each will be explained later in this section :  Autopass  Password Prompting Page 18 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 19 Note: The AT%An command is automatically written to NVRAM. It does not require you to send &W. WARNING: Do not insert spaces between commas or between fields and commas. Spaces will invalidate the command. Page 19 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 20 Courier Lite 56K Business Modem dial back the device at that number Disable dialback AT%A0=password,y,n,, AT%A0=wombat,y,n,, Note: To enable Dialback, you must enable Dial Security with Prompting. See step 6. Page 20 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 21 Note: You must use the &W command to save the settings in NVRAM. If you don’t, the next time you reset or power off the Courier Lite 56K Business Modem, Dial Security will be disabled. Page 21 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 22 When the host has Password Prompting enabled, it asks guest users for a password. The host modem checks the received password against each of its act ive Security accounts. Page 22 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 23 If the guest did not enable Dial Security, the host will not accept the call unless prompting is enabled on the host Courier Lite 56K Business Modem. Page 23 of 94 Copyright © 2018 USR, a Division of UNICOM Global...

Page 29 1. Send AT&M0&N3S14.0=0 to prepare the modem for testing. This command disables error control, fixes the connection rate at 2400 bps, and makes the modem return to command mode when you type +++. Page 29 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 30 This command disables error control, fixes the connection rate at 2400 bps, and makes the Courier Lite 56K Business Modem return to command mode when you type +++. Page 30 of 94 Copyright © 2018 USR, a Division of UNICOM Global...

Page 32: Reference
The modem displays the value of an S-Register, as a decimal value between 0 and 255. The modem, however, understands the decimal value as a collection of binary digits (bits). Page 32 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 33 Starting with a string of eight bits, assign each "1" bit a value based on its position. Add the values to come up with the final decimal value. Here’s an example of how bits are converted to decimal values: 01001111 + 64 = 79 Page 33 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
Page 34 Counts and stores the number of rings from an incoming call. Stores the ASCII decimal code for the escape code character. Default character is “+”. A value of 128-255 disables the escape code. Page 34 of 94 Copyright © 2018 USR, a Division of UNICOM Global...
