- Some tips on using high speed modems under HP-UX:
-
- 1) Do not use both RTS/CTS and XON/XOFF flow control simultaneously
- on the modem.
-
- 2) Lock the interface speed on the gettydef entry.
-
- 57600 # B57600 SANE CS8 ISTRIP IXON TAB3 HUPCL
- # B57600 SANE CS8 ISTRIP IXON TAB3 HUPCL
- #login: #57600
-
- so that a framing error does not change the speed to the port.
-
- The inittab entry for this would be
-
- ttp1:2:respawn:/etc/getty -h <ttyname> 57600
-
- where <ttyname> is of the form tty00, for /dev/tty00, etc. The first
- field (in this case, 'ttp1') must be unique in the inittab file.
-
- 3) Set the modem configuration such that the modem's serial port will
- not change speed. The way that this is performed varies from modem
- to modem, and you should refer to your modem manual for this information.
