Dan Smith's D-RATS Testing

Hardware

Tested on the air with K7TKK and 0.1.6
Sent a file from Windows with (previously-misbehaving) USB-to-serial adapter with success. App-controlled XON/XOFF flow control worked with Windows/USB perfectly
Also transferred some forms with success

Tested on the air with KE7FTE, K7TKK
Was able to exchange files with K7TKK over a range of 10 miles with no errors
Still had an issue with K7TKK's USB-to-serial adapter, but a conventional serial port worked fine

Tested on the air with KE7FTE, N7AAM, K7TKK -- Major Success
Was able to exchange files with KE7FTE (both ways)
K7TKK's ACK and Data blocks seemed to not be transmitting until the mic was keyed
Uncovered some further cosmetic and error-condition issues

I was able to send 30+ kilobyte binary files over the air with the DDT protocol. This was using 9600 baud and a real (i.e. non-USB) serial port.
I have been able send from a physical Linux machine to a Win32 VM successfully (thus showing the buffering issue is definitely gone)
I seem to be having trouble with the radio and USB-to-serial adapters. I have three that all use the pl2303 chipset and all of them have major problems sending data at 9600 (but only over the radio). Not sure if it's the linux driver or something related to the actual devices.

I conducted an on-air test with K7TKK, N7AAM, and N7QQU
Multi-user chatting seems to work well
File transfer from Linux to Win32 with 0.1.2 failed (due to some known buffering issues)
File transfer from Win32 to Linux with 0.1.2 worked well

I was able to successfully perform file transfers over the air (at 4800 baud) using YMODEM and an image file using d-rats-0.1.2.

I implemented and tested the automatic QST functionality successfully.
