poor uucp performance & telebit driver settings

[mel]

Sometime back somone mentioned some rules about "prepending" lettters to
the phone number(?) such as "U" to initiate UUCP register values into the
S111 register.  This applied to the dialTBIT driver in SCO Xenix.  There
were other letters in this table to set this and other registers.  Does
anyone have a complete breakdown of this driver and have more specific
info on how to use these settings?

I'm sure many of these slowdown problems may be related to incorrect S111
register settings.
