Choose older MULTIPORT version, because lastest bde version
not worked.
Don't force HUPCL for bidirectional case.
From bde:
Use bit (1 << (16 + 4)) in schedsoftcom() to avoid clash with
non-serial h/w on IRQ4.
Allow FIFO_TRIGGER in config.
Clear com->mcr_image when clearing mcr for init of 4port. The
usual value MCR_IENABLE should have broken 4ports unless
something happened to clear it later.
Turn off interrupts as well as DTR after an error waiting for
carrier (bidir dialin case).
Drain fifo more carefully.
Don't hang up if debugging.
Rearrange siointr() -> siointr1() for multiport case for speed,
lower latency and clarity.
Use suser() to check perms.
Provide missing splx() after failed perms checks.
c_ispeed == 0 means c_ispeed = c_ospeed (POSIX).
Set parameters (except speed) for c_ospeed == 0 as well as
hanging up.
Better initialization for console (fifo stuff...).
Misc. cleanups.
Fix dead hang if modem power is off.
problems in the moment are stray intr's in the ifconfig up/down.
No way to select all three interfaces on a combo card with
AUI/BNC/UTP interfaces and the performance doesn't look good.
Only tested with a ISA AUI/BNC card yet.
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
Entries for 800 and 820 fixed.
From vak@kiae.su:
incorporate Joerg Wunsch formatting code
correct handle timeouted operations
fixed entry for 720 media
GAP values changed suitable for possible format code addition.
Read/write GAP always 2 now.
Interleave parameter added for possible format code addition.
Many logical formats added.
720K physical drive added.
Problems: still can't read 720..820 media in 1.44 drive.
800K in HD 5.25in (maximum for DD diskettes)
1.44M in HD 5.25in (for easy distributions)
1.46M in HD 5.25in (maximum for 5.25)
Some cosmetique changes.
Now minor looks like UU DDDDDD, UU - unit, DDDDDD - density.
If density == 0, CMOS-detect format assumed.
Fix attach code for correct work with unknown CMOS
floppy types.
Trick diskerr to handle new minor.
1.722M floppy in 1.44M drive popular format added.
possible end-user errors.
Now:
1) on physical 1.2 can open logical 1.2, 720, 360H
2) on physical 1.44 can open logical 1.44, 720
3) on physical 360 can open logical 360
All other variants refused.
C-style improved in this check, multiply if's changed to switch.
More work to add 720K floppy support.
Restore good old dependance of device and floppy type.
Now:
fd?a == 1.44
fd?b == 1.2
fd?c == 720
fd?d == 360 in HD
fd?e == 360
Add more strict size check in Fdopen, not it refuse:
1) Attempt to open any type expect fd?e, if you have only 360K drive.
2) Attempt to open fd?a if you have only 1.2 drive.
added to probe.
2) Force CLOCAL=on for outgoing ports and CLOCAL=off for
incoming ports into open in bidirectional case.
3) Add DELAY after writing to com_ier for fifo drain into probe.

Changes between EPSILON and RELEASE of FreeBSD have again caused
the kernel to not see my floppy disk drives. I don't know what happened,
'cause I don't see any changes to fd.c, but here is an old fix that
I have applied to the probe routine which will solve the problem (at
least for me). Since this is a rather brute-force solution - I understand
if you want to ignore it...
[Upgrading to pre-Beta FreeBSD caused this on my system. -AM]
