DOSTEST.EXE V1.1

Description:
DOSTEST.EXE is a utility for DOS. It can test up to 20 COM ports at the time. It allowes
port specific settings:
- Base IO address
- IRQ ( shared )
- Fifo type ( currently supported are 450 and different variants of 550,650,750,950 )
- Baud rate 1-921600 bps
- Frequency factor (Example: 1 for 1.8MHz crystal and 8 for 14.4MHz)
- Receive FIFO level.

Usage:
dostest [-v] <portdef> <portdef> ....

-v  verbose flag.

<portdef> has the form:
 <com io>,<irq>,<fifotype>[,<baudrate>[,<freq. multiplier>[,<rcv fifo level>]]]
or 
 @<filename>

<com io> is the base address of the com port.
<irq> is the irq channel for the COM port.
<fifo type> one of 450,550,650,750,950 ( currently only 450 and 550 supported with 
					 different fifo lengths)

<baudrate> - and baud rate from 1 to 921600 if not present 57600 will be used.
<freq. multiplier> - cristal frequency as factor of 1843200 Hz. when not present 1 will
                     be used
<rcv fifo level> - a number 0-3 0 - 1 byte trash hold, 3 - highest trash hold ( depending on
			measured FIFO length.

<filename> a file that contains <portdef> one per line.
empty lines are ignored. #-character at the beginning of the line is a comment.

For VScom PCI cards shvsc.com can be used to obtain port configuration.

Example
dostest -v @vscom400.tst

The file vscom.tst contains following lines:
0xE800,9,550,230400,8,3
0xE808,9,550,230400,8,3
0xE810,9,550,230400,8,3
0xE818,9,550,230400,8,3
