- This is interesting. On page 16 of the RISCos 4.50 Software Binary
- Release Notes it says
-
- "The tty1 port on the RC2030, and all tty0 and tty2 ports, except
- for the tty0 port on the Rx3230, have no modem control signals
- (DTR, DCD, DSR, RTS, and CTS) at all. Therefore, these are not
- suitable for use with dial-in or dial-out modems."
-
- If I'm reading that correctly, then both serial ports on the 2030
- are not capable of being used with modems. If tty1 does use the
- RTS/CTS lines, then why was the above printed in the release notes?
- Was there a subsequent hardware change?
