Understanding Result Codes

A result code is the modem response to a command. It may be issued in either of two possible
formats: words (the long form, also known as verbose) or numeric characters (the short form,
represented by digits). The result code format is set using the Vn command:
V1 for words (default)
V0 for numeric characters

In the online mode, the transmitting modem receives characters from the computer, converts the
data to analog signals, then transmits these signals over the telephone line.
The process of altering a signal for transmission is called modulation. The receiving modem
receives analog signals from the telephone when in the online mode and converts or demodulates
the signal, returning it to the digital form that can be used by the computer.
