&Bn – DTR/TX Dial Option
Supported by: TDW-33 TD-36 TD-36 485 TR-36 TR-36B
Description:
This command enables the modem to dial a number which is stored with AT&Z0
commands. This is performed when the DTR signal goes from inactive to active signal
level or when data is received on the DTE TX line (in command mode).
After enabling the Hotcall functionality the modem must be restarted for the function to
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
