USB synchronous serial port - Stein Erik Andresen - 18:04 30-04-04



I'm looking for a synchronous serial adapter for USB. The device will
be used for HDLC communication (framing only) on a laptop (no PCMCIA
available, just USB). Preferably RS-232 / V.24 interface. Does such a
thing exist?

S.E.

  Not sure as a finished boxed product, but at the chip level, look
at STm's new STR7 family.

These ARM cored microcontrollers have USB plus HDLC capable UARTs.
HDLC does not show on the radar very often these days.
