Here's why:
The only pins connected are
Tx (transmit)
Rx (receive)
RTS (request to send)
CTS (clear to send)
The following pins are not connected and can not be used for flow control
DTR (data terminal ready)
DSR (data set ready)
RI (ring)
CD (carrier detect)
DTR is wired to digitizer, messing with it will blank screen.
DSR is wired to the battery indicator.
On the OmniGo, the built-in serial port is COM 1 and the PCMCIA serial port
is COM 4.
Q. Can I use hardware flow control on the OmniGo?
A. Yes and no. Yes you can use RTS/CTS, but you cannot use DTR.
On the OmniGo, DTR is always high, but when the transceiver isn't powered on,
the external DTR pin isn't driven. Since the pin is floating, it will most
likely appear as neither HIGH nor LOW.
