- Has anyone else noticed the following?
-
- When I connect to another system with PC-NFS 4.0 (or 4.0a) telnet, if
- I am running csh on that system, and I am in LINEMODE (cf. PC-NFS 4.0
- Reference Guide, p. 125), which seems to be the normal case (for a
- sample including one Cray, two Convexes, and one Sun), then:
-
- No matter what erase character is defined (^h or ^?), that character
- is passed through to the remote system, and the remote system does
- not apply that erase character, but complains that, e.g., 'ls^h^h' or
- 'ls^?^?' are not recongized commands. If I switch to character mode,
- however, then the erase character defined on the remote system is
- recognized and applied.
-
- Hypothesis: in character mode, character processing is done on the
- remote system, and naturally the defined erase character erases. But
- in LINEMODE, 'character processing is done on the local system, under
- the control of the remote system. When input editing or character
- echoing is to be disabled, the remote system will relay that
- information.' (PC-NFS 4.0 Ref. Guide, p. 125).
-
- Could it be that the remote system is telling the local system
- (PC-NFS telnet) that it SHOULD do input editing, but the local system
- is taking the command to mean the reverse, and ISN'T doing input
- editing? Then perhaps what I am seeing is PC-NFS telnet blythely
- passing along the erase characters, instead of applying them locally,
- and the remote telnet assuming that all erase characters have been
- removed, and objecting to all those spurious ^h and ^? characters?
-
- If this isn't the case, what other possibility might I be
- overlooking?
