- Geoff's Top Ten Reasons for Modem-Related Errors:
- -------------------------------------------------
-
- (10) Cable does not support pins 4 and 5.
- (9) RTS/CTS handshaking not enabled in the modem.
- (8) RTS/CTS handshaking not enabled in the terminal program.
- (7) XON/XOFF handshaking not disabled in the modem.
- (6) XON/XOFF handshaking not disabled in the terminal program.
-
- (These next 3 apply mostly to PC-compatible systems, especially under DOS)
-
- (5) Swapping a 286 between real & protected mode causes IRQ response delays.
- (4) Floppy & Perstor ARLL controllers block IRQs for long periods.
- (3) DOS 'multitasking' swaps comm program's serial driver out of memory
- (and can't put it back before another byte arrives).
-
- (2) Slow CPU or heavily loaded system can't handle incoming data rate.
-
- ... and, of course, the ultimate excuse:
-
- (1) God has decided that those computers talk just too damned fast.
