As discussed in the online help (select "Help->Help Topics..", then 
Source Window and Source Window Pop-up Menus), this is the intended 
behavior.

I'll leave to others more familiar with ARM support in gdb to address 
your other concerns. I will add, though, that I have never had any luck 
using ARM's rdi implementation (which they gave to gdb, no longer 
maintain, and are no longer interested in seeing kept up to date) at 
anything but 9600 baud.

What host/target are you using? I assume it's probably windows-hosted 
using rdi?

Yes, it works at 115200.  I have done it and other have as well.

The ARM AEB board (the $150 board they used to sell) has a bug in it and it would not follow the protocol so switching to a higher speed fails (thus it only works at 9600).
We tried to ask ARM about this and the answer was that we should buy the new $250 development board.

With the current versions of Cygwin it should work fine.


But if you are using a b.20 or some other old version of Cygwin you may encounter problems with serial lines.  It gets worse the higher the speed you use.
In this case, just grab the latest Cygwin and everything will be fine.

Or switch to Linux, and everything will be even finer.  ;)

I use RDI at 19200 (EmbeddedICE) and 38400 (Jeeni) with no
problems under Linux.  The serial/parallel combination also
works well under Linux, though Ethernet (Jeeni) is really the
way to go.

I've heard that serial RDI support under Widows/Cygwin has been
flakey in the past (and not worked at all under some versions
of Cygwin).
