Pin 8 on the RS 232 is either ignored or followed by the SSC card. Assuming this is the same for your serial card, there should be a dip switch which controls whether or not carrier detect is enabled. You should try setting the switch to "IGNORE" or "DCD detect disabled". See if this works. You might also want to see if the terminal ready lead (I believe it is pin 6 offhand) is ignored. >So I try a short BASIC program to see if it works from there.

As far as I know, once you send the card into terminal mode, it is running a program (read/write loop) separate of basic. Try taking out line #20 in the above program. You might want to put in a "PR#2" too, otherwise it will definitely hang on line 30. Hope this helps!
