Description:
This command enables the modem to dial a number which is stored with AT&Z0

level or when data is received on the DTE TX line (in command mode).

take affect. Disable the TX Hotcall function by sending an escape sequence ’+++’ to enter
command mode and then set the &Bn command. See also AT&D and AT&K
