8863.0. "CRTSCTS support on D-U V4.0/AS 2100" by JRDV04::SURUGA () Mon Feb 17 1997 23:08

One of our customers wants to control serial line (RTS, CTS) on 
AlphaServer 2100 running Digital UNIX version 4.0*.  To do this,
I would like to confirm following: 

1)  Does serial port for this server support full modem control ?
	I've heard that some machine does not supprot modem control 
	any more.  I looked at the installation/owner's guide, but
	it does not have this info.

2)  Does Digital UNIX V4.0* support CRTSCTS ? 
	I read in somewhere stating that Digital UNIX V3.2* does not
	support CRTSCTS but will be in V4.0*.  Is this true ?

If Digital UNIX V4.0* supports CRTSCTS, is there any sample program or 
document around which I can give to the customer ? 

Also they want timming chart for this serial line.  Does anyone have it ?

Thanks,

K. Suruga

We support full modem control on both ports of the 2100 and as of V4.0* we
support hardware flow control (RTS/CTS). To enable this feature you need to
set the CRTSCTS line attribute either by using the stty utility (see man 1
stty)
or issuing the termios ioctl tcsetattr() (see man 4 termios).

As far as timing charts for the uart goes we have none.
