Pacsat Upload for Linux and X-Windows
This program has been run using the 1.0 version of the
Linux kernel with the patches from Alan Cox to provide AX.25
encapsulation in the SLIP protocol(verion 0.12).
The TNC must be setup for KISS protocol.

History:
0.1 initial version. G0ORX
0.2 added output ready notify code. G0ORX
0.3 fixed error conditions - back to IDLE. G0ORX
0.4 fixed restart upload of partial file. G0ORX
0.5 converted to Xaw. G4KLX
converted program to use a child process to upload file.
0.6 added double click for upload. G4KLX
