Setting Up Multiple TerminaIs
Owner's Manual
Your TRS-XENIX system is programmed to accommodate a wide
range of terminal types -- but the system has to know what
kind of terminaIs you're connecting to it so that it can
calibrate itself to the terminal's particular
characteristics and capabilities.
Your console is automatically set to accommodate two DT-l
terminaIs. TRS-XENIX calls them the "Adds25" terminal type,
and expects the terminaIs you connect to be set to the
DT-I's Adds25 emulation mode. That information is stored in
a TRS-XENIX file called /etc/ttytype. If you're connecting
a DT-l to your console, just follow connection instructions
and proceed directly to enabling your terminal (see
following). If, however, you're connecting a terminal other
than a DT-l, you have to let TRS-XENIX know.
A file called /etc/termcap stores the characteristics of aIl
commonly used terminaIs. The following list gives the names
and codes for the terminaIs pre-configured in /etc/termcap:
NAME
VT 100
VT 52
ADM 3a
ADM 5
Televideo 910
ADDS 25
CODE
vt100
vt52
adm3a
adm5
tvi910
adds25
To let TRS-XENIX know what kind of terminal you'll be using,
edit the /etc/ttytype file to include one of the above
names. At that point, TRS-XENIX can work with your terminal
-- just as soon as you've enabled it.
