I received a problem report today from a user who was trying to get CANDE running and was seeing truncated message outputs. The error turned out to be outdated instructions in the CANDE setup page on the wiki.

The page stated that the emulator uses 112-character buffers in its Data Communications Adapter (DCA), but in fact that was changed in release 1.04 (late 2016) to 56 characters. The change was made to support the R/C editor that runs under the DC MCP.

The wiki has been corrected. The correct SYSDISK/MAKER deck to configure TS MCP datacom for CANDE is this:

?EXECUTE SYSDISK/MAKER 
?DATA CARD
