Bit Pad Two 27
Send Configuration
Command:
Switch Setting:
Use the Send Configuration command to send a report to the host that identifies the data
tablet model and its version of software. The output looks like this:
MM1103_BIT_PAD_II_by_Summagraphics_Version_n.n<CR><LF>
The underlines are spaces; n.n is the version number and the line feed is switch-selective.
Transmission Control
Command: Switch Setting:
The Start Transmission and Stop Transmission commands act as gates, allowing reports to
be sent or not sent from the Bit Pad Two to the host. These commands control data flow,
regardless of the report mode. (Stop Transmission and Start Transmission are equivalents
of the transmission protocols XOFF and XON.)
Stop Transmission places the data tablet on standby. It is useful for systems that do not
constantly use the data tablet. End the standby state by sending the Start Transmission
command.
If a report is interrupted by Stop Transmission, no data is lost. The report is severed at the
end of the byte. When the Start Transmission command is issued, the next byte in that
report is sent, intact. To avoid corrupted data, the host software should not look for a
phasing bit at the beginning of resumed transmission.
