Hi there,

is someone using a PCMCIA Modem or Serial Port card with an MPC8xx system?

I build a kernel for a TQM860L based board enabeling CONFIG_SERIAL=y
as the PCMCIA HowTo states. (I also have CONFIG_SERIAL_CONSOLE=y). But
while booting (or insmod serial.o) I get :

CPM UART driver version 0.04
ttyS0 on SMC1 at 0x0280, BRG1
ttyS1 on SMC2 at 0x0380, BRG2
pty: 256 Unix98 ptys configured
Serial driver version 5.05c (2001-07-08) with no serial options enabled

Any ideas?

Thanks a million!
