- I have a solution to getting a SupraFaxmodem v.32bis modem to work with a 720
- using HPUX 8.07. First, you need the patch to the operation system,
- PHNE_1440. I recieved it from my local sales rep, but he also said that
- this is usually the responsibility of the Response people (right!). This
- patch does many things, but most importantly it allows hardware hadshaking.
- With this done, the device files created by sam need to have 8 added to the
- minor number at which point they look like this for me (port B 38400 baud).

- I set the modem with the following command:
-
- AT &F2 s0=1 &w
-
- The inittab entry is:
-
- a1:3:respawn:/etc/getty -h ttyd00 38400
-
- The gettydefs entry is:
-
- 38400 # B38400 HUPCL IGNPAR PARENB ICRNL IXON OPOST ONLCR CS7 CREAD
- ISIG ICANON ECHO ECHOK ISTRIP IXANY TAB3
- # B38400 SANE CS8 ISTRIP IXANY TAB3 HUPCL
- #login: #38400
-
- I think that is all that needs to be done. I called in with another v.32bis
- modem (not from Supra) from a mac and the modems connect at 14400 baud with
- full data compression/error detection and logged in successfully. I tried
- to get the hp to talk to the modem at 57600 buad, but couldn't do it.
- If anyone knows how to get that to work let me know!
