I have 2 emdedded devices (let's say A and B) that will have to communicate via RS232
cable.
A is a Java ME (IMP-NG) programmable device and B is a "closed device" that speak this way:
DB9F Pin utilized:
2 RX
3 TX
4 DTR -> it must be set to +Vcc
5 GND
7 RTS -> it must be set to -Vcc
Vcc=3 - 12V
How to configure programmatically the java environment to provide power suppy on the pin DTR / RTS ?
Neither JavaME CommConnection Interface or hardware specific interface seems to do the job.
That's the A device hardware specification (page 27)
Suggestions?

When I have had to interface with a specialized device like this in the past I have had our electrical engineer make a custom cable which provides power on the pins specified by the spec of the specialized device.
