- CUTCP uses a strict interpretation of both the VT102 and Telnet specs. The
- Telnet spec says a telnet connection is seven bits only unless Binary mode
- has been negotiated, while the VT102 docs say that a VT102 can only handle
- seven-bit data.

- No. You have to understand that there's more than one "eight bit graphics"
- character set, too. Which one do you need? Do you want ISO 8859-1, IBM
- Code Page 437, DEC Special and Graphics characters, or something else?
-
- In other words, the way the extra 128 characters is implemented will vary
- depending on what the program author is trying to do. In CWRU-PC/IP Telnet,
- I chose to implement eighth-bit-set characters in a flexible manner, but
- the default configuration is ISO 8859-1.
-
- >Are there any pc implementations of tcp-ip that support eight bit characters?
-
- Yes. CWRU's supports eight bit traffic, and I believe Kermit does, too.
- I'd be surprised if WATTCP's INT14 redirector did not, although you will
- have to find an eight-bit-capable term program to run on top of it.
