I posted some quieries about SBus terminal boards to the net a while back and got some good replies. I will be summarizing in the near future, as soon as I do (or do not) find a solution to my present problems. I finally chose the Sun SPC (Serial Parallel Controller) board. It may have been a mistake. I want 8 more Sun internal ports. No dialin/out cababilities and the like needed. I mostly have terminals plugged in to my Sparc. My my modem software only needs the standard SIGHUP and CD detect signals to work. PROBLEM: I am having some serious flow control problems. Example: emacs /etc/termcap (read-only) and hold down the left or right arrow keys. After a few seconds emacs is beeping saying "Buffer is Read-only". What is happening that the arrow escape code is loosing the escape so emacs thinks I typed OC (or whatever). The system is also crashing. I came down this morning (we installed it yesterday) and the machine was hung. It crashed 2 times yesterday and the ports crash individually also. No syslog messages. Of course we *do* have a big project due Wednesday :-|. PLEA: I would be interested in talking to *anyone* who is successfully using the Sun board with 9600 or 19200 baud text terminals. BACKGROUND: Sparc 1+ running SunOS 4.1. SPC driver as a loadable device. Wyse 185 terminals with normal settings, standard null-modem cables (2-3 3-2 4-5 5-4 6-20 7-7 8-8 20-6), ms=crtscts in gettytab, soft_carrier and str_assert in stc_defaults, NO XON-XOFF!!

Aside from this, I have not #&$^$*@% idea what the #&&$$( is going on. Thanks, gray gray%antr.uucp@med.pitt.edu
