How to Gen in your Maxpeed SS8+

The entire line of Maxpeed serial boards is controlled by a single driver, SY:LHMXSS8.REX. The "plus" models are identical to the original SS4 and SS8 except that they have full modem control and support higher baud rates. You have to include a /PLUS on the DEVICE=TT line to tell the driver that it's a "plus" board.

An SS8+ looks like two SS4+ boards to TSX. The RAM address setting for the second "board" is at the RAM_ADDRESS of hex 2000 higher than the base setting for the board. In our example we will assume (and we downright recommend) that the board is set to ram address D0000. Ready?

DEVICE=TT/HANDDEF=LHMXSS8/CONTROLLER=D/PLUS/RAM_ADDRESS=D0000
    UNIT=1/SPEED=38400/NAME="SS8+ #1"
    UNIT=2/SPEED=38400/NAME="SS8+ #2"
    UNIT=3/SPEED=38400/NAME="SS8+ #3"
    UNIT=4/SPEED=38400/NAME="SS8+ #4"
DEVICE=TT/HANDDEF=LHMXSS8/CONTROLLER=E/PLUS/RAM_ADDRESS=D2000
    UNIT=1/SPEED=38400/NAME="SS8+ #5"
    UNIT=2/SPEED=38400/NAME="SS8+ #6"
    UNIT=3/SPEED=38400/NAME="SS8+ #7"
    UNIT=4/SPEED=38400/NAME="SS8+ #8"

What you see here is that we have told TSX there are two "boards", both of them essentially SS4+ models. The driver must program each virtual board with unit numbers 1-4 (actually, internally, 0-3). You will of course have more qualifiers for each unit such as /CMDFILE and so on. By the way, if you did not buy that SS8+ from Dan at S&H, you paid too much!
