Hello all! Have anyone experimented with the Commodore serial 'IEC' routines? I'm currently trying to convince the C64 to print an ASCII SEQ textfile out to an MPS like printer. The character conversion is not much of a problem, but the serial I/O is. For me, it's like opening the floppy file (SETLFS, SETNAM, OPEN), then describing that it's the default input (LDX lf, jsr CHKIN). Then opening the printer (SETLFS, SETNAM, OPEN) and CHKOUT. And then calling CHRIN, converting the char, then CHROUT until BIT6 of ST (ST after CHRIN) is cleared. Only problem is: the thing does not work :-(. It prints the text out to the screen, if I don't call the printer open routines at all - but definitely fails to write to the printer, with an - interesting thing - ST=$42 after the first calling of CHRIN. Anyone having a clue what I should do in order to get it to work? Thanks, L. - This message was sent through the cbm-hackers mailing list.
