With TCP/IP working under OS/2 I went looking for the next thing that I’ve always wanted, and that is a good modem emulator. Funny enough SIO the COM driver replacement for OS/2 actually includes this functionality.
And has for years… I just never knew it.
I know in the NT centric would we live in today, it’s all moot, but I thought it was really interesting for those of us that still hinge on modems… And freaky hardware, since OS/2 can let some things talk directly to the hardware without OS/2 drivers (IOPL=YES).
So for the sake of it, I downloaded version 1.60 of SIO, went through the install, then added a virtual modem as described to my config.sys .. And I placed a test ‘call’ with OS/2’s terminal program, and I was talking to my MUD!
So I thought I’d try something crazier, like load up a BBS, then configure it for four modems!
And it worked!
Sure there are some slightly easier to configure ways to achieve this (DOSBox includes modem support), and I suppose the better thing to do would be to give virtual modems to Qemu. Then OS’s with no TCP/IP can benefit from this.
