Does any one have personal experience with using MCSP on a Sony Vaio? The Vaio has no RS-232, only USB ports, so to use the bootloader I have to use a USB to RS-232 adapter.

MCSP seems to load fine but any time I try to compile and program it comes back with an error message something like "can't open COM4".

Tera-term works a treat and opens COM1 but MCSP seems to try to open COM4.

How do I direct MCSP to COM1??

Cheers
Brian
