Yikes! I'm ready to finally get some USB<>RS232's
A local just told me that in his experience, the Prolific chips were trouble free.
As I read your post, some Prolifics only send their serial data upon receipt of a CR (in the data buffer). This sounds contrary to reason since it should send any byte it is presented with. It may only send CR/LF delimited strings of bytes...?
So if I don't use CR (like for Icom radios or other binary data streams) it won't send until a $0D happens to appear in the binary data stream.
Something wrong with this picture

In normal CONVerse TNC mode this isn't a problem since each packet ends with a CR and/or LF.
I'm not aware of any receiving problems with USB adapters though.
