I assume the question was to redirect output from an existing
application program for which no source code was available, to
a disk file. If you wanted to capture incomming stuff off the 
serial ports, KERMIT might be more convenient than PIP.
CP/M does not treat IO devices the same as files like
UNIX, so one can not easily ( with out hacking your bios,
) capture IO into files. I can imagine a small utility
sitting under CCP capturing calls to RDR or whatever,
and writting a log file. However, many CP/M programs using serial
ports go directly to the hardware, so there is still a
problem. Can you be more specific as to the capability needed?
