**** VCom v0.1b **** (1 port inbound telnetd) NOTE: Because this program will be shareware or maybe commercialware, it supports a maximum of 40 connections (not simultaneously). After 40 users have telnetted to your site, you must reboot to reset the counter. Installation ------------ 1. Add a device statement in your system.ini for vcom.386: [386Enh] device=x:\vcom\vcom.386 2. If you want a base address other than 2a0h and/or irq other than 7, then specify the base address and irq for the virtual com port in your system.ini: [vcom.386] port=2a0h irq=7h NOTE: In this version no error-checking is implemented on port/irq selection, so choose a port and irq that is not in use by another device. You can find valid candidates by right-clicking on "My Computer," selecting properties, selecting the "Device Manager tab," and double-clicking on "Computer." In future multi-port versions, all ports will share a single irq. 3. Reboot your computer. After doing so, launch vcom.exe and then the DOS application that you would like to virtualize. 4. Test your program by telnetting to 127.0.0.1. Virtual Modem Commands ---------------------- All AT commands other than "ATA" return "OK," and "ATA" returns "OK" if a ring has been detected or "NO CARRIER" otherwise. "RING" and "CONNECT ..." messages are also returned by the virtual modem. "ATH0" and "+++" are not supported, so the remote party must disconnect, which will return a "NO CARRIER" message. Bugs ---- I am aware of most of the bugs in this version, but I have not had time to fix all of them. Future Enhancements ------------------- I am defering the addition these features in anticipation of the Win95 DDK. Significant performance improvement Multiple ports (on 1 irq) Outbound connection via "ATDT " ".VxD" rather than ".386" with dynamic loading Caller ID (?)
