[Xastir] Serial Port Questions

[Bennett, Joe]

Hi Everyone,

I'm curious if anyone else has seen this type of action with Xastir and 
a KPC3+ (v9.1)

When I connect my KPC3+ directly to ttyS0 I see delayed packets being 
IGated to the APRS-IS:


20061003000000,KA3NAM-9>S8UT8R,WIDE1-1,WIDE2-1,qAO,KC0NYQ-1:`zIal!ok\]"7G}Escape'n

20061003000130,KA3NAM-9>S8UT8R,WIDE1-1,WIDE2-1,qAo,KA3NAM-10:`zIal!ok\]"7G}Escape'n 



When I connect the KPC3+ via a USB to Serial adapter I get something 
like this:


20061005134640,KC5YTI-3>S8US9Q,WIDE1-1,WIDE2-2,qAO,KC0NYQ-1:`zMam_V>/"7@}

20061005134640,KC5YTI-3>S8US9Q,WIDE1-1,WIDE2-2,qAo,KA3NAM-10:`zMam_V>/"7@}g


(the extra "g" I think is an issue with the USB adapter... Various 
characters show up in that position when using the USB adapter)


If I connect my TNC-X to ttyS0 or USB adapter, the problem goes away. If 
I connect my KPC3+ to AGWPE (on WinXP box) and have Xastir connect to 
AGWPE, the problem goes away...


My initial thought was that there may be an issue with the handshaking 
since I seem to recall that even in KISS mode, the KPC3+ uses 
handshaking (even though the spec. does not call for it)... Somehow the 
KPC3+ buffer is not being dumped in the scenario outlined 
above??????????????????????? Dunno.... Weird thing is that the TNC-X 
does not have the issues when connected in any configuration... This 
leads me back to the KPC3+ as the culprit...?????




Ideas, thoughts, experiments???
