The stock serial ports usually will drop characters when run at
high speeds with incomming data. The best way to fix this is to
add the "FAS" driver to your system. (FAS stands for Final

allows operation at high speeds without loosing characters.
+ SCO Unix, ESIX, and ISC UNIX are all reputed to support the 16550

8. Is there a port of X11 R3/4 available for whatever?
X11R3 is available from all of the 386 UNIX distributors.

+ 25. Where can I get the K-Shell (aka ksh)?
+ There are several sources where one can obtain a working ksh for 386
+ based systems. These include the following:
+
+ * get source from the AT&T toolchest (approx $3,000 for a full
+ site license)
+ * get the MKS trilogy (approx $130) which includes a home-grown
+ substitute ksh.
+ * get gnu-BASH which has lots of the functionality and is free.
+ * get the KSH from Aspen Technologies
+
+ At least one of the System V R3 releases (namely Microport) included
+ a ksh. The base port of System V R4 includes the ksh as one of its
+ standard shell, so if you wait a bit, it will be part of the base
+ system.
