I emailed David Sainty a while ago and he kindly sent me the full version of 
TequilaComm.  However, he asked me not to release it because it had a problem 
with the help system.  Apart from that it works very well, although 19200 
baud does not work reliably for me - it tends to hang.  Since 9600 is fast 
enough for me when doing terminal emulation (for large file transfers I use a 
GoMMC) I have not tried very hard to get 19200 to work.
