Ray Gwinn’s comm drivers for OS/2. SIO.SYS and VSIO.SYS are replacements of the OS/2 communications drivers COM.SYS and VCOM.SYS which come with OS/2. VX00.SYS provides FOSSIL and virtual 16550 support for DOS programs. SIO can be ordered to support any number of ports. Vmodem now has both inbound and outbound Telnet.
VFD is a Virtual Device Driver providing FOSSIL functionality to VDMs (Virtual DOS Machines) running under OS/2. It does this by translating FOSSIL API calls (from a VDM) into OS/2 file system calls.
