Could the problem be compounded by the LPT1 port?
Seems to me that printers print a lot slower than they receive data. Also
printers have their own buffers. Therefore, printers are designed to
accepting chunks of data sent at high speed but sporadically. That would
lead computer designers to give the LPT1 port a very low priority compared to
other tasks and communication going on in the computer -- the printer is so
slow the data can always catch up.
Now if you're keying the rig through the LPT1 port, wouldn't the port
continue to behave the same way? Since CW (or any communication meant to be
transmitted on the rig) is sent to the rig in "real time" and at a fairly
slow rate (1200 bps - 9600 bps), anything other than full and complete access
to LPT1 makes a big difference at the rig. There are no buffers in the rig
to hold data and you don't have any delay like a slow printer.
Would the serial port behave better? Can WriteLog be configured to use a USB
port? I am neither a computer not a WriteLog expert but leave the issues to
others who may be able to shed some more light (not flame) on the issue.
