USB->Serial Ports on the Lombard
Long story short...is it possible to communicate with devices that want the old RS422 serial port on this computer.
Specifically, I'd bought the Lombard 333Mhz (OS 9.2.2) for the purpose of setting up a MOTU Midi Timepiece II. The MTPII has the RS-422(geoport, serial, 8DIN) connection but I discovered that the Lombard doesn't. No problem I thought so I also bought a Compu-Cable Mini-Geo USB to serial port adapter but that caused the computer to lock up whenever I searched the idock ports with the MTP unit turned on, otherwise it says it doesn't see anything on the port(s).
The MOTU unit is not suspect because I have another known good model and I get the same results when attempting to access it. The geo-port adapter seems to be installed correctly.
I've seen it mentioned that on comparable desktop models some sort of Stealth card needs to replace the internal modem.
I'm new to macs but very experienced with PCs. Is there a way to change settings or disable conflicting devices to make this work? Try a different OS or adapter, or am I SOL?
