You will have to buy a special serial card; the standard serial ports on a PC can only be configured for 115200. Note that at the speed you suggest a 16550 UART will be generating around 15,000 interrupts per second. This will place a _serious_ load on your system, and if you're using IDE disk, may cause you to suffer communications problems. Unless you're building a dedicated router, I'd suggest looking for an alternative solution. > Michael -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
