Using TiLP, which appears to be the best thing available, with a SilverLink cable to link with a TI-86, I get one of these errors:
"Msg: Unable to open COM port.
Cause: Check that the device is not used/locked by another application (modem ?).
System: GetLastError = 6 -> The handle is invalid."
or
"Msg: No I/O resource available !
Cause: several ways. Check for:
- PortTalk device driver (parallel/serial cable under Win NT4/2000/XP)
- TiglUsb device driver (SilverLink)."
