I had the very same problem with the uucico on my SparcStation 1. In fact
I actually patched the uucico-binary to get a timeout of 64 seconds instead
of the hard-coded(!) 45 seconds. Here is the program I used:
#include <stdio.h>

long offset = 14128l;

/* This is only for SunOS 4.1.1 Sparc */
int value[100];
main()
{
int buff[100];
int i;
FILE *fpin;

	fpin=fopen("uucico.patch","r+");
	fseek(fpin,offset,0);
	fread(buff,25,1,fpin);
	for(i=0;i<25;i++)
		printf("%04x ",buff[i]);
	fseek(fpin,offset,0);
	getchar();
	buff[5]=(unsigned int)0x90102040;
	for(i=0;i<25;i++)
		printf("%04x ",buff[i]);
	getchar();
	fseek(fpin,offset,0);
	fwrite(buff,25,1,fpin);
	getchar();
	fseek(fpin,offset,0);
	fread(buff,25,1,fpin);
	for(i=0;i<25;i++)
		printf("%04x ",buff[i]);
	}
}

It was pretty hard to find the right place in the binary to patch.
Also, if someone knows a good program that does binary patching
on arbitrary files using command line arguments I would be glad
to have it since I don't want to write a C program every time
I patch something :-)

>Thank you!
 Hope I could help.
