SIO.SYS
The Sio.sys driver is a replacement for the com.sys driver. The Sio.sys driver can support up to 16 COM ports.
DEVICE=\OS2\BOOT\SIO.SYS <parameters> DEVICE=\OS2\BOOT\SIO.SYS (Cn, An, In, Ig, Fc)
- CN
The number of the Com port or the string COM1 to COMn. If you use a * in front of the Com port, then the port will be used as a PCMCIA Com port.
- AN
A hexnumber to define the I/O address of the Com port.
- IN
The IRQ number (0 to 15) or the string IRQ0 to IRQ15. If you don't use this parameter, SIO will search for a IRQ.
- IG
This exists only for compatibility with COM.SYS and is ignored by Sio.sys.
