Any digit or symbol (0- 9, *, #, A, B, C, D) may be dialed as touch tone digits. Characters such as spaces, hyphens, and parentheses do not count- they are ignored by the modem and may be included in the dial string to enhance readability. The following may be used as dial string modifiers: L Redials last number. Should be the first character following TD, ignored otherwise. P Pulse dialing T Touch-tone dialing (default). V The modem switches to speakerphone mode and dials the number. An ATH command may be used to disconnect the voice call. , Pause during dialing. Pause for time specified in Register S8 before processing the next character in the dial string. W Wait for dial tome. Modem waits for a second dial tone before processing the dial string. @ Wait for quiet answer. Wait for five seconds of silence after dialing the number. If silence is not detected, the modem sends a NO ANSWER result code back to the user. ! Hook flash. Causes the modem to go on-hook for 0.5 seconds and then return to offhook. ; Return to command mode.

The range of n is 0- 3. $ Bong tone detection. The dial modifiers listed above (except S) shall be saved when dial strings are stored. The T and P modifiers are allowed anywhere in the dial string so signaling methods may be changed after some digits are already sent. En Echo Command. En controls whether or not the characters entered from your computer keyboard are echoed back to your monitor while the modem is in command mode. 0: Disables echo to the computer. 1: Enables echo to the computer (default). Result Codes: OK n=0, 1 ERROR Otherwise Fn Online Echo Control. Fn determines if the modem will echo data from the DTE. This modem does not support the F0 version of the command. However, the modem will accept F1, which may be issued by older communication software, to assure backward compatibility. 0: Online data character echo enabled (NOT SUPPORTED, ERROR). 1: Online character echo disabled. Result Codes: OK n=1 ERROR Otherwise Continued Addendum 255318-001 to Guide 284820-001 19
