Serial Interface<\/i><\/p>\n
    \n
  • a complete computer on its own leaving the Amiga free for other tasks\n
      \n
    • 65CE20 @ 3.58 MHz controls the I\/O operations<\/li>\n
    • has 4 times the computing power of a C64<\/li>\n
    • 16 kB RAM<\/li>\n
    • the RAM is addressable by the MC680x0<\/li>\n<\/ul>\n<\/li>\n
    • seven 8 pin mini-DIN serial ports\n
        \n
      • not completely RS232C compatible, the RI signal (Ringing) is missing<\/li>\n
      • has jumpers for each port to exchange the RxD (Recieve Data) and TxD (Transmit Data) lines – nullmodem mode without using special cable (setting both jumpers either outside or inside on the jumper block for each port)<\/li>\n
      • seven adaptor cables with DB25 RS232C compatible serial ports supplied (80 cm long)<\/li>\n
      • 50-19200 bps transfer speed for each port<\/li>\n<\/ul>\n<\/li>\n
      • the card is capable of 115200 bps mode but only with the supplied software<\/li>\n
      • up to five A2232 can be installed into one machine giving a total of 36 serial ports<\/li>\n
      • supported by Amix, NetBSD (normal and turbo modes) and OpenBSD<\/li>\n<\/ul>\n
