MacX & MacTCP: "unimplemented co-routine error 12" (11/94)


I am running a Macintosh Portable with MacTCP and MacX. When starting up MacX, I get the error message "unimplemented co-routine error 12." I get the same error message when I try to use NCSA Telnet without MacTCP. The same configuration worked on other Macintoshes.

Do you know of any problems using these two software components on a Macintosh Portable?

The problem may be improper installation of CommToolbox, MacTCP, and/or MacX. We tested both MacX and NCSA Telnet 2.3 on a Macintosh Portable and didn't have any problem. Here are some things to check:

- Make sure that the CommToolbox is properly installed and that the
"Communications Folder" folder was created in the "System Folder".

- Make sure that the "MacTCP" and "AdminTCP" CDEVs are in "System Folder"
and that the "MacTCP Tool" comm tool is in the "Communications Folder"
folder.

- Make sure that all MacX fonts are installed in the "MacX Fonts" folder.

- Make sure that MacTCP is properly configured on the network.
