It also keeps you from using the psuedo-ttys for other purposes for which a
getty is not needed, such as "usemouse" or the X window client "xterm".

I wonder if this will change now that Lachman is a part of Interactive (or is it
the other way around)?

If you are using an alternate mail transfer agent (smail2.5, smail3), installing
SCO TCP/IP does a fair job of munging your mail system.  When installing
SCO TCP/IP, be prepared to re-install your alternate mail software right after
installing TCP/IP, or you will have mail problems.  The easy solution to this
would be for SCO to make SENDMAIL one of the selections on the installation
package menu, so you can choose not to install any of the SENDMAIL programs,
or related programs that go with it.

smail3 compiled just fine with the SCO TCP/IP Dev Sys.  I haven't tried
anything else, but should be working on porting, or writing, some TCP/IP
sys admin software in the near future, so I'll know much more once I get
into that.

Even using an 8-bit card, the SCO TCP/IP seems to perform very well.
