Solving Configuration Issues
Connection Type
The default connection type is set to INF_EXT (auto). For the 3COM
ISA card, this implies the card setup program has been used and has
setup the card connection type. If you are unable to communicate with
this card and netstat -in shows the device, the connection type may be
incorrect. To correct it, you may do one of the following.
1. Use the 3COM setup disk to configure the card for the connection
used.
2. Change the OS-9 device descriptor for the type of connection in use.
