+ added PMCOM library - RS-232 DOS communication library by Peter Marinov.
The original PMCOM 1.0 library has not been updated for very long
time and this code is quite strongly modified so I haven't tried to
generate any .diff files. I do not think it will be possible to make
autoamtic merege with newwer version (if any appears).
This is also the reason I decided to use HBPMCOM name instead of
PMCOM to avoid potential conflicts with some local versions of
this library.
TODO: add support for flow control - now flow control functions are
dummy and do not enable any handshaking.
* harbour/src/rtl/hbcom.c
* harbour/config/dos/watcom.mk
* harbour/config/dos/djgpp.mk
+ added support for serial port in DOS builds (hb_com*() PRG and C API)
using HBPMCOM library.
