- To Install SIO, unzip or place the distribution files into a directory
- that is NOT named SIO and type INSTALL, followed by return.
-
- I now have a basic web server at www.gwinn.com for SIO registration
- and registered user updates.
-
- Please note my new CompuServe ID, 72662,3547.

- This release of SIO (version 1.60) corrects a problem is VSIO.SYS, and
- a problem with ESP detection that was introduced in the previous
- release. Additionally, support has been added for newer 16550s that
- support bit rates to 460800. Also see HISTORY.TXT.
-
- Many newer mother boards and Super I/O IDE controller cards have
- 16550s that supports bit rates to 460800 bps. SIO now recognizes
- these 16550s and will allow bit rate settings of 230400 and 460800
- bps. If at boot time the message "Detected 16550A" displays in green,
- then you have one of these newer 16550s and can use the higher bit
- rates. Since many programs do have selections for these bit rates,
- you may have to lock the bit rate in the SIO command line.
-
- Tell the application developers that IOCtl function 63 hex can be used
- to determine the maximum bit rate for a port, then they can adjust the
- selectable bit rates automatically. This function works with either
- SIO.SYS or COM.SYS.
-
- The green 16550s should be able to share IRQs, but I have not tested
- this. It is also interisting to note that 460800 bps is a faster
- transfer rate than a floppie disk.
-
- The SIO support BBS is available via Internet using VMODEM or Telnet.
- The Internet address is vmbbs.gwinn.com. Note that you will NOT
- normally be able to download using most telnet clients. However,
- using VMODEM and your favorite terminal program, you can download
- using telnet connections.
-
- Many users have reported problems when using the USR Sportsters. One
- user reported that the problems when away when he installed the latest
- firmware upgrade from USR. He also noted that one default setting
- were changed and may be a clue. The default of &S1 was changed to
- &S0.
