SymDriver-U
is a device driver to allow applications to use the WAN. Symdriver-U provides
pathways through the UNIX kernel. These pathways allow any application
to have Streams access to the X.25 WAN (via Symicron's DTSX adapter),
and may also be used as routes for TCP/IP. Using this access methodology,
the application an connect to resource on the far side of the WAN.
|
In
order to run SymDriver-U the user must have previously installed:
 |
UNIX variant, either:
AIX RS/6000, AT&T
Dell SVR4, HP 9000 / 700, Interactive, Solaris Sparc for Sun,
Novell Unixware, Solaris Intel or SCO

|
Symicron's
DTSX-9, -22, -26, -27, -29 or -30 |
