- This may help. I had to do some research on running Reflection, a terminal
- emulator package, on TCP/IP.
-
- In the pre-Windows days, terminal emulator programs could
- be written to be well-behaved, meaning they did the std. comm port call to
- the BIOS, invoking DOS' int. srv. rtn. to actually go out and read and write
- from the comm port. I believe this interrupt was called int 14.
-
- Good TCP/IP packages, such as Novell's LAN Workplace for DOS or FTP's PC/TCP,
- provided int 14 support. This meant that they had a TSR which allowed you to
- read and write to a network connection exactly as if you were reading and
- writing to a serial port. And they slipped in the address of THEIR routines
- into the int. vector table, so when your well-behaved terminal emulation
- program made its read or write interrupt call, it was *REALLY* reading and
- writing to the network connection. It was blissfully unaware that it was
- going across the network.
-
- I'm sure I'm simplifying, but if your terminal emulator is well-behaved
- (i.e., doesn't muck directly with the serial ports) and your TCP/IP package
- provides this support, it should be just a matter of configuration.
-
- And in these days of Windows, I'd expect to see the same trick pulled soon
- with DLL (Dynamicly Linked Libraries).
-
- Also, the new version of Procomm Plus is supposed to have network support.
