FOPEN won't open COM-ports?
Hi,
I have tried to open a comport (VFP5, Win98), but I cant' make it work.
I have tried handle = FOPEN(COM1:)
and
cPort = 'COM1:'
handle = FOPEN(cPort)
and I have tried with or withour colon, with or without COM1: in brackets or not, as well as adding modus parameter, but of course sometimes I get an error message, but all the time, without exception, the handle returned is -1, indicating no success.
Furthermore, I have yet to find out how I can define the transmission speed (I won't say 'baud rate', since baud per defintion IS a rate...)
Hope somebody can clear this up for me.
Rolf
