Has anyone had any real success with the IBM 3151 terminals under SCO Xenix? We have the 'latest-greatest' version of termcap from SCO. They seem to feel everything is working fine. But we have misc. screen garbage, cursor hops (just seems to move by itself but is very repeatable). We are using SCO Office Portfolio etc. I personally use the system from a shell all the time and the terminals still act unreliable. As an example if we 'stty tabs' the terminal flips out. If you do: 'stty tabs;df -v' the screen will clear/home and display only some parts of the df. We are running the terminals off of a Model 80 with the Digiboard C/X terminal concentrators. I have experienced these types of problems at another customer site and always attributed it to not having the terminal reference to tune the termcap.. Well now I have the 500 page reference and haven't the slightest idea were to start.. BTW we are trying to run the terminals at 38,400 but I even turned them down to 300 baud and got the same results.

It sounds to me like your flow control, if any, isn't working properly
and you're sending data (particularly control codes) faster than the
terminal can handle it. I've had similar problems with IBM 3164s. Try
doing tests that send a few escape sequences (the more they do, the better;
clearing the screen and tabbing around might be good choices) and then run
a command that sends several lines of output. If you start losing bits,
then it probably means that you're sending data before the terminal has
finished processing the control codes.

Yes well I have tried running the terminals at 300 baud. And It doesn't seem to make a difference. If these terminals have flow control problems at 300 baud then we need a big dumpster..

I use an IBM3151 on an Intel 386 running XENIX 2.3.3 and don't have any problems at all ... here's my setup: Machine Mode IBM3151 Screen Normal Row and Columns 24 x 80 Scroll JUMP Auto LF OFF Line Wrap ON Operating Mode ECHO Line Speed (bps) 9600 Word Length 8 Parity NO Stop Bit 1 Turnaround Character ETX Interface RS-232 Line Control IPRTS Break Signal (ms) 500 Send Null Suppress ON Enter RETURN Return FIELD New Line CR Send LINE Insert Character MODE And here is the termcap entry that I use: ib|ibm3151|ibm3161|IBM 3151/3161 terminal:\ :am:mi:cr=^M:sf=^J:co#80:\ :it#8:li#24:kI=\EP\040\010:cd=\EJ:ce=\EI:\ :cm=\EY%+\40%+\40:cl=\EH\EJ:dc=\EQ:dl=\EO:do=\EB:\ :le=\ED:mb=\E4D:md=\E4H:me=\E4@:mk=\E4P:\ :mr=\E4A:nd=\EC:se=\E4@:so=\E4A:ue=\E4@:\ :up=\EA:us=\E4B:ka=\E\0401:kA=\EN:kb=^H:\ :kC=\EL^M:kd=\EB:kD=\EQ:kE=\EI:kh=\EH:kP=:\kN=:\ :kl=\ED:kL=\EO:kr=\EC:kS=\EJ:kt=\E1:ko=^I:kO=\E2:\ :kT=\E0:ku=\EA:k1=\Ea^J:k2=\Eb^J:k3=\Ec^J:kw=\EI:\ :k4=\Ed^J:k5=\Ee^J:k6=\Ef^J:k7=\Eg^J:k8=\Eh^J:\ :k9=\Ei^J:ti=\E>A:te=\E>A:po=\E^P^R:pf=\E^P^T:ve=:vs=:vi=:\ :bx=\354\361\353\370\352\355\367\365\366\364\356: Now I have experienced a certain "jerk" when running the 3151's at 38.4K, but other than that, all has been well.
