SIO.SYS: Difference between revisions

Latest revision as of 17:31, 29 August 2021

The SIO.SYS driver is a replacement for the COM.SYS driver that supports 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.
