		use the command \N5 to enable V.42/MNP/Buffer error control while the
		Intel product uses \N3 to provide similar functionality.
		This V.42/MNP/Buffer mode attempts to negotiate V.42 error control with
		the remote modem. If this fails, the modem changes to MNP, if this fails,
		no error control is used. This field is not case sensitive. Default is upper
		case.

		sensitive. Default is upper case.

		field is not case sensitive. Default is upper case.
	Dial Type	This field controls the type of interregister signaling to be used between
		the modem and the Central Office. The field has a default of ”T“ for tone
		dialing. Pulse dialing is indicated by “P”. The field length should be 3
		characters long. This field is concatenated with the dial string. This field is
		not case sensitive. Default is upper case.

		break for communication within the United States and Canada. The option
		&P1 sets a ratio of 33% make and 67% break for the United Kingdom and
		Hong Kong. This field has a blank default and a 5 character long entry.
