Serial Solutions Using NewMode
<address> Backwards compatibility only
is a hexadecimal I/O address in the range 0 to FFFF
eg 03f8 for COM1, 02f8 for COM2, 02e8 for COM3
Note: Do not set the i/o address this way.
Use /A on the device= NewCOM.SYS line in
CONFIG.SYS file.
<irq> Backwards compatibility only
2...15 or -1 is the interrupt line to use.
Note: Do not set the irq this way.
For standard serial ports use /I command on the
device= NewCOM.SYS line in CONFIG.SYS
For shared interrupt multiport serial cards use
/L command on the device= NewCOM.SYS
line in CONFIG.SYS file. file.
Since the <address> and <irq> settings have been
superseded by switches in the CONFIG.SYS file, only the
communications parameters, <params> should be given with the
newmode command. The <params> specified may be none, any
or all of the <baud>, <parity>, <databits> or <stopbits> options.
Unspecified values are replaced with defaults as follows:
Baud rate 1,200
parity even
databits 7
stopbits 1 (or 2 for 110 baud)
Examples._________
c>newmode com1:300
sets COM1 to 300 baud, even parity, 7 data bits and 1 stop bit.
c>newmode com3:11,n,8
sets COM3 to 110 baud, no parity, 8 databits and 2 stop bits.
c>newmode com2
sets COM2 to 1,200 baud, even parity, 7 databits & 1 stop bits.
