What follows are some of the known test mode commands for the Oki 900 (or AT&T 3730) cellular telephones. The commands can be issued after the test/debug mode has been activated. Notes: Hit CLR to erase a wrong keypress. The data following a command is sometimes required to be entered in decimal format, and sometimes in hex. Non-numeric hex data can be entered with two keypresses as follows: *, 1 = A; *, 2 = B; *,3 = C; *, 4 = D; *, 5 = E;*, 6 = F.

"Although street rumor indicates that the Oki 900 is no longer being manufactured, the popularity of the small phone stems from the Cellular Telephone Experimenter's Kit (CTEK) developed by Mark at Network Wizards of Menlo Park, CA. The CTEK is a small box and cable that allow the phone to be controlled by software through the serial port of any PC [see review in the Dec. '93 issue of Nuts and Volts]. The CTEK essentially converts the standard EIA-232D serial data to the proprietary format required to communicate with the Oki via the data port on the bottom of the phone. Included in the bottom of the phone is a source code library so that programmers can create their own custom software to control many of the phone's functions. The most popular software being created for the phone are scanning programs which cause the phone to decode the cellular phone numbers and other information from the cellular network's forward control channels."
