Re: [maverick-devel] Eliminate echo on BASIC 'IN' statement

[Robert C. <rob...@gm...>]

Hi Steve,

The mvIO class has a setLocalEcho(boolean) method to switch on and off
local echoing.  If somehow you could find out from the telnet daemon
wherher to do echoing then all you need to do is call this method to
enable or disable local echoing.

Ages ago i think i looked at it quickly but with the old version of
the telnet daemon could not see how to determine echo status.  This
might be fixed in latest versions of the telnet daemon.
