1998/07/29  Version 0.5
----------

Driver now supports up to 4 yam modems.
yam0 default to COM1 0x3f8 irq4
yam1 default to COM2 0x2f8 irq3
yam2 default to COM3 0x3e8 irq4
yam3 default to COM4 0x3e8 irq3

1998/09/01  Version 0.6
----------

Added : bitrate/baudrate configuration.
Added : mcs file may be loaded from yamcfg.
	One mcs file is affected to each bitrate.

		mcs data for 1200 and 9600 bds are preloaded in the driver
		but may be changed by yamcfg.

options of yamcfg :

  [iobase <iobase>]
  [irq <irq>]
  [bitrate <bitrate>]
  [baudrate <baudrate>]
  [duplex <mode>]
  [hold <delay>]
  [txdelay <txdelay>]
  [txtail <txtail>]
  [slottime <slottime>]
  [persist <persistence>]
  [load <bitrate> <filename.mcs>]

/proc/net/yam gives the current configuration


1998/09/12  Version 0.7
----------

A patch to the kernel tree 2.0.36 has been created.
To patch the kernel, do the following :

cd /usr/src
cat PATH_OF_THE_FILE/yam08-2.2.1-patch.diff | patch -p0

cd linux
run "make menuconfig" (or other) to configure the yam options.

------------

The program yamcfg get or set the parameters of the yam driver
yamcfg -h gives a minimum help

Example setup of yam0 for 1 serial port (com2) :

  file /etc/ax25/axports :
  port0 F1OAT-9 9600 256 2 VHF  (9600 bit/s)

  commands :
  setserial /dev/cua0 port 0	# to avoid conflict with yam driver
  insmod yam
  yamcfg yam0 io 0x2f8 irq 3
  ifconfig yam0 hw ax25 f1oat-9 up



Example setup of yam0,3 for 4 serial port (com1->com4) :

  file /etc/ax25/axports :
  port0 F1OAT-9 9600 256 2 VHF  (9600 bit/s)
  port1 F1OAT-8 9600 256 2 UHF1 (9600 bit/s)
  port2 F1OAT-7 9600 256 2 UHF2 (9600 bit/s)
  port3 F1OAT-8 9600 256 2 UHF3 (9600 bit/s)

  commands :
  setserial /dev/cua0 port 0	# to avoid conflict with yam driver
  setserial /dev/cua1 port 0	# to avoid conflict with yam driver
  setserial /dev/cua2 port 0	# to avoid conflict with yam driver
  setserial /dev/cua3 port 0	# to avoid conflict with yam driver
  insmod yam
  yamcfg yam2 irq 5
  yamcfg yam3 irq 7
  ifconfig yam0 hw ax25 f1oat-9 up
  ifconfig yam1 hw ax25 f1oat-8 up
  ifconfig yam2 hw ax25 f1oat-7 up
  ifconfig yam3 hw ax25 f1oat-6 up



Good test !!!
