SYMPTOMS
When you attempt to connect two computers using the Direct Cable
Connection tool (DCC), you may have the option to select an LPT port. If
you select an LPT port and it is an infrared (IR) port, the connection
does not succeed and you may receive any of the following error messages:
- Waiting to connect via cable on LPT<n>. Is the host computer running?
- Cannot connect to the host computer. Make sure you have Direct Cable
Connection on the host computer and you have connected your cable to
both computers.
CAUSE
The behavior occurs because the IR port is a unidirectional port. DCC
requires that LPT ports be bidirectional.
RESOLUTION
To work around this behavior, use an IR COM port instead of an IR LPT port
for IR communication between computers.
