There are plenty of examples of flow control using either in-band or out of band signalling within the channel and just using two or four wire connections. Any rational adaptor (serial to optical) should be capable of interfacing to the full collection of control lines on a serial port - tx/rx, ctr/dtr, and cts/hook at a minimum. Of course, whether the IRDA interface implements those things to the driver is another question :) _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
