I'm looking for one to connect to older MIDI interfaces, Palms, old Macs, and other oddments. USB to serial interfaces won't cut it for Localtalk or MIDI

It will not support variants of the serial port such as:
* AppleTalk

* Geoport

* MIDI devices

* External clocking (All Laser printers and most color inkjet printers)

A quick Google indicate's that's pretty universal.
