Not really, no... it seemed your usual sort of

now you mention it...

I'm moving on now to the 4046 PLL setup, coz it's set for a centre frequency of about 4.5kHz, which is far too high.

I shall have to redimension things a bit... to bring it down to say 2.5kHz...

Well, I've done that & it does appear to receive stuff...

After much frigging around with pixel counts, it displays stuff.

Oddly, the timing seems very variable... I can't decide if VB is dropping characters or if the PIC16F88 is sampling randomly... I find it difficult to believe that the pic could be as far out as it looks on the screen... but I may well be wrong there.

It is indeed very odd... if I make the display window larger, the timing goes all to pot...

How weird is that?

Down to the speed of the pc, I've migrated the code on a floppy over to a slightly faster machine & the scan rate doesn't change any more.

Since it's running XP, however, the serial handling seems to have slowed to a crawl...

I gave a load of old books including a beginner's guide to VB3 to the Barnardo's charity shop last year. If you hurry Z it may still be there.

Thanks, Xogg, I'll pop along tomorrow morning. Probably gone though...
