Instead of trying to change the source code of Talk85, you could change the
modem's S-register #3, which stores the carriage return (CR) character, to
the line feed (LF) character. To do this, execute the following:


1. Hook the external modem to your computer.
2. Run a terminal program and type the following command: ATS3=10 S4=13
3. Connect the modem to your calc via Graph-Link and null modem cable.
4. Run Talk85 and everything should be spiffy, with Enter working as
carriage return.


Here's technical BS explaining why this works (from my USR Manual)


S-registers control modem setup defaults. The default setting for carriage
return is stored in S-register #3 as the ASCII code 13. The ASCII code for
Line Feed is 10, stored in S-register #4. By switching S-register #3 and #4,
you in effect switch the CR and LF characters, thus letting Enter serve as
CR instead of LF.


Since I own neiter and external modem, Graphlink-85, or a null cable, I
can't test this, but from what I know about modem commands, it ought to
work. Someone please try it ant tell me if it works or not.
