1. Install a communication program, e.g. conex, on the HP200. Port=com1, speed=19200, bits=7, full duplex, XON/XOFF. Do not exceed 19200 baud. Using a serial cable is preferable to installing a network card for prolonging battery life.
2. Connect to Serial port using the black 9 to 25 pin adaptor in the HP connectivity pack. Cable lengths of at least 100 feet are usable at 19200 baud.
3. Change each port on the Jameco 4 serial port card to a different IRQ by changing the jumpers.
4. Comment out any serial lines in inittab.
5. Add the following to /etc/rc.d/rc.serial:

   /bin/setserial /dev/ttyS2 irq 11 /bin/setserial /dev/ttyS3 irq 12

6. Make sure rc.serial is being called from rc.M .
7. reenable ttyS1 in inittab:
   s2:12345:respawn:/sbin/agetty 19200 ttyS1 vt100
   The 19200 is critical for HP200.
8. init q
9. Change BIOS setting on PC (by pressing Del at boot-up)...chipset features. For example:

   device irq port address com1 mouse 4 ttyS0 3f8 com2 remote terminal 3 ttyS1 2f8 com3 - 11 ttyS2 3e8 com4 ext. modem 12 ttyS3 2e8

10. Change BIOS settings in chipset features to disable the serial ports on the motherboard:
    onboard serial port 1: disabled
    onboard serial port 2: disabled
    
11. Check links:

    lrwxrwxrwx 1 root uucp /dev/modem->cua3 lrwxrwxrwx 1 root root /dev/mouse->ttyS0

12. Type 'conex' (or the appropriate command for your DOS terminal program) on the HP200 - you should immediately get a login prompt after hitting Enter.
13. Also, change external modem initialization string to

    ATZ\r AT&F\r AT&C1 M0 &D2 &Q5 &K3 W1\r

    
    This works better for Cardinal modems than the string in the manual.
