Hi All,

I am using RComm to receive data on a BT RFComm connection.
I am a bit counfused about Read()

Is it possible to avoid the use of a termination character?

The way I have it working is that it only reads if the input is terminated by the termination character specified in TCommConfig.

Does it always need at least one termination character?
I tried to set iTerminatorCount to zero in TCommConfig, but it didn't help.

ReadOneOrMore seems not to have this problem, however I would prefer to use Read to be able to set a timeout..

Any suggestion?

Thanks,
Enrico

Why are you using RComm for BT RFCOMM communctions??  Why are you not using RSocket??

Because all I really need at this point from BT is the serial port functionality I thought TComm was appropriate..

Anyway, I got the point, so I rewrote the program using RSocket and "hardcoding" the BT Address of the device I want to use and it seems to work! Smiley
Thanks for the suggestion!

What are  the virtual comm port settings? Is it possible to change them?

The API isn't designed to be used in that way (direct from RComm that is) which is probably why your having problems.

The settings I belive (i'd have to check back in the office tomorrow) are 9600 8n1.  You can change them, but I belive the driver just ignores what you do (again, i'd have to check - I personally always stick with the defaults).

Re: RComm::Read and termination char
Didster... can RComm port be used in this way to send data over a CSD connection between two phones?  I have such an application... everything seems to go okay... except that when I have send about 25K of data out... the sender stops working... not sure why.

For this program, I start a CSD connect...loan the data port, configure it for 9600/8/n/1 and then start calling write() async... when runl is called, I go and send the next block... this continues until I have sent about 25K and then it just stops....

any ideas?  should I be sending using sockets?

Thanks
