Re: [Beowulf] Re: multiport RS232 to ethernet (or USB)

As a student hiding in the corners and under the stairs on this list i was wondering why you guys would want to be connecting things to your marvelous clusters with RS-232 type ports. i mean there's many other ways to interface right? So what'cha plugging into these contraptions?

And, I suppose one could gang up a raft of $9 USB/Serial dongles on a USB  hub (somehow, I suspect that this is fraught with peril)

The device has to allow independent control of RTS and reading CTS (which  may not be used in the usual flow control scheme)

 

 

It might be a tall order to get the ":cheap" $9 USB to Serial adapter to do Request to Send / Clear to Send / hardware handshaking ... probably should consider Xon / Xoff / software handshaking instead = not a problem for the least expensive USB to Serial adapters. (Ctrl S / Ctrl Q being easy from the command line or script to get the port to respond.)
