The serial port on my A410/1 simply refuses to send data anymore.
(it was working, and now it ain't). I've checked out the cable, and
attempted to do a back-to-back, with no joy.

So, rather than spending mega-$$$ on getting my machine repaired (and
worse, being without it for ages), I was wondering:

a) About a year ago someone posted saying they had ended up socketing one
   of the serial related chips because it failed so regularly - if anyone
   has the details then I'd like to check this out, please.
  
b) Can anyone tell me if the Serial Port twin-serial card has
   software to allow one port to behave transparently as if it were
   the internal port? I'm very tempted to buy this card for two
   new serial ports that work, rather than have the broken
   one repaired for quite probably a similar amount of money...

Can't remember the exact chip, but would most likely be the serial driver,
25LS32 (?) possibly. Look near the serial connector!

Nope, sorry it doesn't. The II card which did a similar thing doesn't work
like that with Risc OS 3.1 so they're having to take the 'transparent' mode
out. Hopefully everyone will support the modular serial driver spec anyway
:-)
