Did you took care about the mode in which the timer0 is running. Its possible that the timer is running as 8 bit timer and not 16 bit as intended.

Question is why does it?
The set up is:
//--------- Serial Communication Set-up ----------- SCON = 0x70; // Set serial communication in mode 01 // (8-bit) and reciever enabled (RI = 1). PCON = 0x00; // Set SMOD0 = 0. T2CON &= 0xF0; // Set timer 2 as baud rate generator. RCAP2H = 0xFF; // Set 9600 baud high. RCAP2L = 0xD9; // Set 9600 baud high. SADEN = 0xFF; // Enable slave address // for automatic address recognition. SADDR = F100ADDRESS; // Address of data byte (0xF3). RCLK = 1; // Receiving baud rate clock. TCLK = 1; // Transmission baud rate clock. SM2 = 1; // Enable automatic address recognition. IE = 0x1E; // Enable timer 1, 0, External 1, and serial interrupts. EA = 1; // Enable global interrupt flag. TR1 = 1; // Start timer 1. TR2 = 1; // Start timer 2. ET1 = 1; // Enable Timer 1 interrupt. EX1 = 1; // Enable External interrupt 1. IP = 0x10;// Set Serial Interrupt as highest priority.
Checking on th 8-16 bit
SCON = 0x70; // Set serial communication in mode 01 // (8-bit) and reciever enabled (RI = 1). PCON = 0x00; // Set SMOD0 = 0. T2CON &= 0xF0; // Set timer 2 as baud rate generator. RCAP2H = 0xFF; // Set 9600 baud high. RCAP2L = 0xD9; // Set 9600 baud high. SADEN = 0xFF; // Enable slave address // for automatic address recognition. SADDR = F100ADDRESS; // Address of data byte (0xF3). RCLK = 1; // Receiving baud rate clock. TCLK = 1; // Transmission baud rate clock. SM2 = 1; // Enable automatic address recognition. IE = 0x1E; // Enable timer 1, 0, External 1, and serial interrupts. EA = 1; // Enable global interrupt flag. TR1 = 1; // Start timer 1. TR2 = 1; // Start timer 2. ET1 = 1; // Enable Timer 1 interrupt. EX1 = 1; // Enable External interrupt 1. IP = 0x10; // Set Serial Interrupt as highest priority.
Isn't that better?
