I need to connect to an HP49G calculator. X-Face: $DD[\LKdx&F)[EMAIL PROTECTED]:I8![L"O*X#'|ctq-w]1aoQD8x1:[EMAIL PROTECTED] From: [EMAIL PROTECTED] (Christopher R. Barry) Date: 02 Jan 2000 11:08:15 -0800 Message-ID: <[EMAIL PROTECTED]> Lines: 44
I think I need help from a serial port guru. I am using ckermit to transfer files between my PC and a HP49G calculator. Under MSDOS, everything works fine. Here are my DOS kermit settings: SET MODEM TYPE DIRECT SET PORT COM1 SET SPEED 9600 SET CARRIER-WATCH OFF SET FLOW NONE SET PARITY NONE SET BLOCK 3 I can then just put the calculator in server mode and from my PC do SEND <file> and it transfers right over. Under Linux I do the exact same thing except I specify /dev/ttyS0 instead of COM1 for the first serial port. When I try to transfer a file it goes to the transfer screen and the errors counter just slowly accumulates. The HP calc indicates that there is serial activity; they just don't get the connection right I guess. Again, this all works perfectly under DOS. My /etc/serial.conf looks like: ---------------------------- ###AUTOSAVE### /dev/ttyS0 uart 16550A port 0x03f8 irq 4 baud_base 9600 spd_normal skip_test /dev/ttyS1 uart 16550A port 0x02f8 irq 3 spd_normal skip_test ---------------------------- Is there some magic I can work with stty and setserial to get ttyS0 as close to the way it is under DOS as possible, or do any of you serial gurus have any connection debug tips or know anything I could try? Thanks very much in advance for any help; I worked on this all day yesterday and all this morning and haven't made progress and am very frustrated.... Christopher
