Did you try if they work on minicom? Almost all standard (AT Hayes
compatible) serial modems work in linux - only some very old (14.400)
Rockwell modems don't! Sometimes you must play with init strings but this is
doable.

Your main problem on 486 is that you must have a 16650 like serial interface
(check dmesg)

Current cdrecordes don't have fine tuning of low speed (1x, 2x, ...)
According to:

 http://www.plextor.be/english/products/pxw482448a.html
 http://www.plextor.be/english/pdf/PlextorVariRec.pdf 
 http://www.plextor.be/english/pdf/PlextorCAV.pdf

your CDR should do at least 4x, 8x, 16x (and in range from 20X upto 48X
covered in 1X steps).

Try then 4x or 8x. On my P200 I have PXWR 8/2/20 and I don't have any
problems at 8x. I think that 24X (3600KB/s) is doable even on P200 (on light
machine load) but it depend on your HDD speed - my HDD IBM-DTTA-350840 in
hdparm test has >8MB/s.

You should connect hdd and cdr to different IDE channels and turn
on DMA for HDD and CDR. I use for disk (only, because my cdr is on scsi:) 

 hdparm -c1 -m16 -p4 -u1 -X34 -d1 /dev/hdb

Use burn-proof technology with cdrecord option driveropts=burnfree :)

There are two missinterpreted (because they aren't related) definitions in
ATA standards:
- physical interface  PIO, S/MDMA, UDMA
- logical (software) acces to data: CHS, LBA (LBA28) and LBA 48bit

As I know all current ATA drives (not S-ATA)  even theoretical 128PiB have
physical interface usable on all plain ATA controllers starting from i386 (or
even i286). Only last ATA-7 standard gives compatybility level for

As I know 2.0.xx and 2.999+3.0xxx have usable postexec :(
