Chapter 14 – Specific AT Commands
Multi-Tech Systems, Inc. CDMA Wireless AT Commands - PN S000294C 103
Custom Character Set +WCCS
Description: This command provides the ability to edit and display the custom character set tables. The
“CUSTOM” mode of the +CSCS command uses the custom character set tables.. In this
mode, when the user enters a string, this string is translated into the CDMA character set
using the ‘Custom To CDMA’ table. In a similar way, when the user requests a string display,
the string is translated from CDMA character set using the ‘CDMA To Custom’ table.
In edit mode, the edit session is terminated by <ctrl-Z> (0x1A), or aborted by <ESC> (0x1B).
Only hexadecimal characters (‘0’…’9’, ‘A’…’F’) can be used; two hexadecimal digits per
character. The number of characters entered must equal the edit range requested, otherwise
the command will terminate with a “+CME ERROR: 3” result.
