I had previously requested that anyone who is running a good async multiport board at reasonably high rates please let us all know about it. Several responses were posted -- thanks!! I am happy to say that I'm now using an ATvantage-X Computone 8-port board on an ALR 386. We've got 5 ports at 38.4kbps which *mostly* work. If you've got big function-key sequences you're blasting at it from a terminal it will not work properly above 19.2kbps. However, I tried the same setup on a Wyse-3216 and couldn't get it to function right *ever*! -- Rob Frye NetExpress Communications, Inc.

Maybe I should add an extra constraint that I neglected, the board has to support hardware flow control. You need that if you're going to hang a US Robotics HST or Dual Standard HST and have things run smoothly. Only two that I know of that support hardware flow control are the Computone and Digiboard. One soul in e-mail told me the Maxspeed does not support hardware flow control, ok, out goes that one. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | Xenix is the ONLY thing ** ARPANET : crash!pnet01!jca@nosc.mil | Microsoft did right. ** INTERNET: jca@pnet01.cts.com ** UUCP : {nosc ucsd hplabs!hd-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

With flow control on 38k terminals are running flawlessly. Using only x-on/x-off at those speeds, some brands of terminals worked, others wouldn't. Don't know you price contraints but if you find a hungry dealer you should be able to get the Anvils for under $1000 for 12 ports. -- Bill Vermillion - UUCP: uunet!tarpit!bilver!bill : bill@bilver.UUCP

Comtrol has had hardware flow control for years, on the Hostess and Ultra series of controllers. More info, e-mail here.

One soul in e-mail told me the Maxspeed does not support >hardware flow control, ok, out goes that one. We've had an Arnet Smartport 8 port board here in indep1 for almost 2 years. It definitely has hardware flow control - it's running a Trailblazer Plus at 19200 on one of its ports without any problems. When doing uucp transfers at 19200, I can see the data lights start and stop every now and then when the hardware flow control turns things off. We just got the new driver from Arnet - all we had to do was give them a phone call. No hassle, no problems, and NO CHARGE!! -- +------------------------------------------------------------------------------+ | Peter Franks | pete@indep1.mcs.com OR pete@indep1.uucp | | NI9D | Use whichever one works | +------------------------------------------------------------------------------+
