Automation Command
Description
SetCommPort
1
<none | pipe
| COMn BAUD>
Sets the mode of communication you want to use with the
simulated serial port.
pipe
Tells the simulator to use a named-pipe as the method of
transport for serial data to/from the simulated machine.
The pipe name will be of the form
"\\.\pipe\SimNow.COMn", where "n" will be 1 for serial
port 1 and 2 for serial port 2. The name is not user
configurable.
COMn
Tells the simulator to use one of the host serial ports
(identified by "n") as the transport for data to and from the
simulated machine. "n" can be any value between 1 and
255, and must be an actual COM port that is present on the
host system. Regardless of the configuration of the
simulated COM port, the host COM ports baud rate is
configured depending on the BAUD parameter, with 8 bit
data, no parity, 1 stop bit. “BAUD” can be one of the
following values (1200, 2400, 4800, 9600, 14400, 38400,
56000, 57600 or 115200). See also Section 11.1, "Kernel
Debugger", on page 155.
none
Tells the simulator to discard any written data, and always
return "receiver empty" on reads.
SetMultiplier nMultiplier
Use the SetMultiplier automation command to specify the baud
rate delay time used to make the serial based communication to
Microsoft‟s kernel debugger in some cases much more stable. A
valid nMultiplier value must be in the range of “nMultiplier>=1
and nMultiplier<=100”. For example to delay the baud rate by
1/00th of normal you would enter “SetMultiplier 1”. The default
for nMultiplier is 100.
GetMultiplier
Returns the current value of “nMultiplier”.

1 simnow> sledgeldt.usage
Automation Command
Description
Link (0|1|2) (0|1)
Enables or disables link 0, 1 or 2. For example
„sledgeldt.link 0 1‟ enables link 0 and „sledgeldt.link 0
0‟ disables link0.
LinkStatus (0|1|2)
Returns the link status of link 0, 1 or 2.
LinkWidth (0|1|2) (8|16)
Sets link width to 8 or 16 bit of link 0, 1 or 2.
GetLinkWidth (0|1|2)
Returns link width in bits of link 0, 1 or 2.
GetConfig
Displays LDT configuration.
LogDMA (0|1)
Enables (1) or disables (0) DMA logging.
