[aprssig] usb - serial

[Steve Noskowicz]

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.
