Upgrading to '486
Last week's IBM '486 on-a-board upgrade announcement was only the
beginning of a flurry of 'we have it too' press releases. AST,
maker of '386 desktop power in various speed ranges (mhz), has also
announced their own upgrade to '486 horsepower. AST systems
feature a passive backplanes with the processor and memory on a
daughterboard. This forethought may be paying off since upgrades
are now so simple that a user can complete them in a matter of
minutes. Other vendors are sure to follow as the '486 speed train
starts to steam roll the used to be high performance standard.
--> Hints for the Power User <--
This weeks edition of our column is oriented toward the SCO Xenix
user.
SCO FOXBASE+ Multi User Database Software
When using SCO FOXBASE+ packages from multiple login id's make
sure you set the "umask" shell parameter to "007" before execu-
ting the package, and insure that you have all users operating
the package in the same login group.
This will prevent files from being made inaccessible to other
users, which may otherwise occur when FOXBASE+ rewrites them
during normal operation.
------
Printing on Local Terminals
SCO Xenix 2.3 can be configured to operate local printers (prin-
ters attached to terminals) by using the 'lprint' command. There
are a few things to note about the 'lprint' command.
1) The terminal in question must be defined in /etc/termcap,
and must have the 'PN' (start print) and 'PS' (end printing)
entries defined. A sample entry is given below for 'vt100'
terminals.
2) Your terminal or emulation software must correctly support
the local print capability. 'QVT-PC' and 'Smart Term 220'
both are capable of doing this on PCs, as well as a few
others.
3) 'lprint' does not translate file formats; output translation
must be done before input is passed to the 'lprint' program.
4) Printing done in this fashion is not spooled.
------
Xenix Modem Control
To temporarily reserve a line which has a modem on it for dialout
without disabling the port, issue the command:
/usr/lib/uucp/ungetty ttyname
When you are done using the port for dialout, and wish to return
it to normal dialin service, issue the command:
/usr/lib/uucp/ungetty -r ttyname

IBM has done it to most of their buyers again. Only certain runs of the Model 70 (I believe it's the Model 70A21) can accept the new processor update. IBM has only shipped some 2,000 of these total; the rest of the IBM buyers are out in the cold on this one. To top it all off, they are supposedly introducing a "new" MCA which is supposed to have the bandwidth that the original MCA was designed for, but never realized. Again, no refit possible for the older users on this one. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 312 566-8911], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.
