need help w/ Hayes ESP serial card and Linux

Post by Glenn A Sacks » Thu, 20 Jan 1994 01:39:52

I recently (ok, yesterday) purchased a Hayes 1-port ESP serial accelerator
"for windows". I guess I shouldn't be too surprised that I'm having
trouble with it in Linux, even though the card is supposed to be backward
compatible with the 16550,16450. I have the card set up as com1 (3F8) using
irq 9 and I am using setserial to tell this to Linux. (Linux does identify
the card as a 16550A upon boot up.) I was previously using my modem on
Com2, so I had to remake the /dev/modem file so it pointed to the right
spot. Using kermit, I can send commands to my modem. I can get it to dial

Is there some other program which tells Linux how to interact with
/dev/modem which I need to change, or is it just impossible to use this
card. I find it hard to believe that if I can send commands to my modem
through this port, that I can't recieve responses back through it. I have
already looked through the FAQ and have not found any help there.

Thanks for any and all help.



1. Help needed configuring Hayes ESP Card

Hello all,
I am having problems configuring my Hayes ESP Card to work under
3.2-STABLE (cvsuped).  So far the only thing I have found in the
handbook has been to add the option COM_HAYES to my kernel configuration
which has been done.  I get the following now on boot:
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A esp_port has com 3
 esp_port has com 3
 esp_port has com 3
 : ESP slave
sio1 at 0x2f8-0x2ff irq 3 on isa
sio1: type 16550A esp_port has com 3
 esp_port has com 3
 esp_port has com 3
 esp_port has com 0

However neither cuaa0 or cuaa1 respond to the Hayes Card's IO devices.
I can't seem to work out if I need to be using another device or if I am
completely off the track.  If someone could point me in the right
direction it would be appreciated.
