Re: [Gpsbabel-misc] Time-out during waypoint download

[Anders A. <sm...@us...>]

Thanks for the feedback; I managed to solve the problem with the
waypoint download timing out under certain circumstances.

The 5-7-character waypoint labels that seemed to trigger the bug
came in data packets 65-67 bytes long.  I think I have seen that
the terminal driver uses 64-byte buffers internally.  A Tektronix
833 data comm tester confirmed that the Garmin unit indeed sent
the entire packets, but the final bytes were indefinitely delayed
in the Solaris terminal driver.

I replaced the GPS unit with a loopback wire, wrote a test program
and found that data packets 1-3 bytes long also suffered from the
same problem, which was due to a weird default MIN parameter value
in the terminal driver for non-canonical input mode.

I submitted a detailed description with my two-line patch to the
Tracker, but unfortunately SouceForge complained about my attached
patch file being of the wrong type, and it didn't make it, so I'll
attach it to this message as well.  If you want me to send the
patch to some other address, just let me know.
