ZOC is an OS/2 32-bit modem communications software package, and a good one at that. SIO is a set of high performance replacement serial port drivers for OS/2. Both of these packages are shareware and can be found at the following location: ftp-os2.nmsu.edu /os2/comm/ 570360 Apr 16 18:43 zoc2052.zip /os2/drivers/ 200981 Apr 10 04:48 sio145a.zip I had been resisting switching to SIO for a long time, as I feel that the registration fee ($25) is too high for a couple of device drivers. However, the documentation which is supplied with the latest version of IBM's SLIP/PPP update specifically mentions SIO as a fix for constipated data transfer rates when using a 28.8 modem. I was able to verify the inability to set the DTE rate to anything higher than 57,600 when using the standard Warp COM.SYS driver, but after switching to SIO.SYS I can now lock in at 115,200. Note that this *doesn't* mean that the modem-to-modem transfer rate will be anywhere close to 115,200. In fact, I previously mentioned that I'm only seeing a modest 60% increase over 14.4 modem data transfer rates. Is SIO worth 25 clams? Hard to say...but the shareware version will allow you to try it for 30 days for free so you can make your own evaluation. -- Karl E. Yeanoplos Denver, CO kyeanopl@den.mmc.com / key@csn.net
