	I just received an Infotel 2400 XA modem which is supposed to
	fully support the Hayes commands.  When I first plugged the
	modem in the "HS" led was lit but the "AA" led was off.

	After reading the manual I entered the command:

		"ats0=1&w0&y0"

	Which turned on the auto-answer mode.  However,  as soon as
	I did this the High-Speed LED went off.  Now whenever I receive
	a call, the modem answers in 1200 mode and I cannot get it to
	operate in 2400 baud mode.

	The manual mentions that I can configure the modem to select
	various operation speeds by entering an AT set command.  The
	only one it mentions is "ATBn" where
			n=1 selects Bell 212A in the 1200BPS mode
			n=0 selects CCITT V.22 in the 1200BPS mode.

	It does not mention anywhere on how to select 2400BPS mode.

	Can someone please help???  How do I select 2400BPS?

	Randy
