I put up a new version (0.6) of SerialClient that fixes some logging problems.   
I've been using SerailClient to talk to a Atmel STK500 (I wrote it to capture the protocol to assist me in writing a Mac program to drive the STK500 directly).    
It also seems to work fine with a loopback on the RS-232 adapter I use. (Keyspan USA-19HS)
If you've tried it and had problems please drop me a quick e-mail and I'll try to resolve the issue.

Added:  The drivers that come with the USA-19HS do not work with Intel Macs.  You must download the beta drivers from the Keyspan site.
