Does anybody have the pinout for the db-9 on the back of an HP 110? Much Grass, -=Paul Flaherty, N9FZX/VK2WYX | "TEXAS! Has a USENET in it... (Lord have Mercy ->paulf@shasta.Stanford.EDU | on us all!)" -- _The Best Little Net in Texas_

The hp 110 pin out corresponds to the DB25 pin out wherever possible. It
was defined before IBM introduced their 9 pin serial which explains why they
are different.
1 DTR
2 TxD
3 RxD
4 RTS
5 CTS
6 DSR
7 Ground
8 RLSD (carrier detect)
9 Ring Detect
HP sells cables for the 110.
HP 92221M ...... modem cable DTE to DCE
HP 92221P ...... printer cable DTE to DTE (wired with nul-modem)

The HP 9000 Series 300 interface was originally based on the HP 110,
and here is what we used (it is now PC-standard male on the 345/375).
