Have you installed any processor intensive programs recently ?
Does the problem go away if you halve the serial port speed ? (or quarter it)
I get Bad FCS errors on my RPC if I run the internal port at 115k2, but get
none at 57k6. I'm sure it hasn't always been like this ...

I get no errors whatsoever when using Connector and doing BBS stuff so I
suspect something in the ANT suite is being very slow/inefficient.
ANT said it was that the modem's serial port wasn't up to 115k2, which is not
the case at all.

Sounds suspiciously like a bad phone connection ie dialing a different
number isn't any better/pretty random occurence. Report it to your telco
and pester them until they do something :). You may get a better response
if you report it whilst you've got the problem so hopefully they will be
able to detect it.

Turn your serial speed down to 57600. This decrease the amount of bad
FCSs by around 98%. I don't know why it happens though :-(

Thanks for the suggestion - i have done that and it doesn't seem to
decrease the transfer rate much, I normally get just under 7000 now i'm
getting just over 6000. Why would that be?

Have you tried using the Green or Colt ROMP?

I can remember the first time I had to go to sleep. Mom said, "Steven,
time to go to sleep." I said, "But I don't know how." She said,
"It's real easy. Just go down to the end of tired and hang a left." 
So I went down to the end of tired, and just out of curiosity I hung a
right. My mother was there, and she said "I thought I told you to go
to sleep."

The only thing that the V.42bis will compress is going to be text, almost all
of the other stuff you come across whilst using the internet (web browsing
and FTP) will be already compressed (ZIP files, GIF, JPEG etc.).
The DCE rate (modem to ISP speed) will be 56K max (if using V.90) so no
benefit gained by using a DTE (computer to modem) speed any higher than this.
(unles you're only using the modem for newsgroups and email).

Because the connection speed between the modem and the computer is now
only 57600 bits/sec, which is around 6000 bytes/sec instead of the 12000
bytes/sec (which is rarely reached due to the speed of the modem).

It could also be caused by a dodgy phone extension, or a contact in a
telephone socket which has become dirty.
