>Release:        FreeBSD 2.1-STABLE i386
>Environment:

	Supra Fax v32.bis modem on 16550 UART

>Description:

	The hayes dialer stalls waiting for a 'connect' code from the modem.
	It usually recovers after the 1st timeout.

>How-To-Repeat:

	re-build tip with the hayes dialer defined in tipconf.h.
	attempt to dial a site defined in /etc/remote.

>Fix:
	
	The second 'gobble("\r");' appears to be the problem, removing it
	causes the dial sequence to work properly.

/usr/src/usr.bin/tip/libacu/hayes.c, line 96:

	write(FD, "ATv0\r", 5);	/* tell modem to use short status codes */
	gobble("\r");
>Audit-Trail:
>Unformatted:
>>>	gobble("\r");
	write(FD, "ATTD", 4);	/* send dial command */
