## Known Problems

Cygwin is still a beta release (20.1, as of Dec 4, 1998) and there are known problems; please refer to the Cygnus documentation page for these. As for GMT, our preliminary testing under Win95 has revealed teh following:

- The I/O redirection seems to have problems when binary i/o is selected. This is likely to be related to the fact that on MS-DOS machines there are both text and binary modes for opening files, but redirection only uses text mode. Thus, when GMT writes binary to standard out there seems to be some contamination with CR/LFs. The workaround on WIN32 platforms is to use the WIN32-specific extension to the -b option: You may append a comma followed by the output file name for the binary data. This redirects the output to that file using binary mode. For example, using -–bod:junk.b writes to junk.b. Note this option is only available when GMT is compiled under Windows.
