hi all,
I thought this could be of some help. i bought a usb (not serial, but they have the serial as well) T191 cable from this online store. It arrived in 3 days.
Hello. Can you check the chipset being used? Is it based on FTDI or Prolific? I have lots of Prolific cables.. but I need FTDI based cables because it's the only way where we can run non-standard baud rates.
Thanks!

The FTDI chips are significantly more expensive than the PL2303, so you will not commonly find them in consumer electronics.
As the T191 cables are intended for low / standard baudrate applications, I would be _Extremely_ surprised if you ever find a cable with the proper 2.5mm plug that has a FTDI chip.
Better to build one yourself, or buy one of the FTDI cables from their webshop and solder your own 2.5mm plug to it.

But beware of standard audio 2.5 plugs, they usually don't fit on motorola phones as their casing is too thick. Use plug and cable of a fitting headset or datacable.
Hint if you don't want to solder, find a usb to serial converter using a FTDI chip - a search for that shows mostly cable-less two-jack cased ones - and connect a standard serial T191 cable.
