WTP Option TPI
WINA registers WTP Option TPI numbers. The number space is divided
into three segments:
-
0x00 - 0x7F: Well-known values, managed specified by the WTP working group
processes.
-
0x80 - 0xDF: Reserved values, registered and managed by WINA.
-
0xE0 - 0xFF: Experimental values, registered by WINA only for advisory
purposes
In order to register an Option TPI, a short description of its use must
be provided.
See WTP 30-April-1998
[WTP] for more information on code page negotiation.
