While you type the AT command, does anything echo? If nothing is echoing, then
one or more of the following is true:

1) You don't have the modem in local echo during command mode. type ATE1.
2) The serial card (internal modem which works *exactly* like an SSC) doesn't
   have interrupts enabled. On the SSC, there is a switch to switch (sw2-6,
   I think) If your card (internal modem) doesn't have this switch, or isn't
   able to generate interrupts at all, then Z-Link is useless to you as I have
   built the entire program around the fact that the computer has interrupts.
   Sorry, but it's simply too hard on my part to work around it.

As for the program crashing after CONNECT, I think I can fix that no problem.
I'm sure it's as simple as my checking the wrong flag somewhere.

Watch for the update that (should) work on the enhanced //e, does VT100 (screen
emulation only - keyboard later), handles a 25th line, and other goodies...
